So, let us get to the definition of class warfare as per the great learning site:
Class warfare:
"...Class conflict, also class war or class warfare, is both the friction that accompanies social relationships between members or groups of different social classes and the underlying tensions or antagonisms which exist in society due to conflicting interests that arise from different social positions. Class conflict is thought to play a pivotal role in history of class societies (such as capitalism and feudalism) by Marxists who refer to its overt manifestations as class war, a struggle that is viewed by them as a product of capitalism..."
and proselytism:
Proselytism:
".. Proselytism is the practice of attempting to convert people to another opinion and, particularly, another religion. The word proselytism is derived ultimately from the Greek language prefix 'πρός' (towards) and the verb 'έρχομαι' (I come). Incidentally, proselytism is prohibited in Greece, according to the constitution of Greece. Historically in the New Testament, the word proselyte denoted a person who had converted to Judaism. Though the word proselytism was originally tied to Christianity, it is also used to refer to other religions' attempts to convert people to their beliefs or even any attempt to convert people to another point of view, religious or not. Today, the connotations of the word proselytism are often negative but this article will use the word neutrally to refer to any attempts to convert a person or people to another faith...."
Well, in simple class warfare within a people of the same religious domain, conflict resolution may be easy. That is assuming that both the 'proletariat' and the 'bourgeoisie' have the same cultural underpinnings.
But when another religion starts chipping into the 'proletariat', wanting them to denounce their former religion with false propaganda and try to ally them with the culture of the new religion, especially when the religion is an alien one, things get murkier. For now, the cultural common ground using which a conflict maybe resolved, is lost. The proselytes, aided by the foreign power grow more aggressive in their demands because they do not identify the 'bourgeoisie' as their own. And again, they have found a new entity batting for their interests. Any punishment of even rogue elements among the rebellious proletariat becomes 'persecution of the religion', the proselytes look to the homeland of the new religion for support, and seeing a chance at expanding its power, the foreign country seeks to establish a stronghold in this new land. What was a simple conflict now becomes a clash between two countries.
For those who think that missionaries are right in converting groups of underprivileged people, or even right in converting anybody at all, I have this from the Bhagwada Gita:
Classifying properties attributable to the good.
Ch. 16
१-३
श्री-भगवान उवाचा
अभयम सत्त्व-सम्सुद्धिर
जनाना-योग-व्यवस्थितिः
दानं दमास का यज्नस च
स्वध्ययास तप आर्जवं।
अहिंसा सत्यम अक्रोद्हस
त्यागः शंतिर अपैसुनाम
दया भुतेस्व अलोलुप्त्वं
मार्दवं हरीर अचापलं।
तेजः कसम ध्र्तिः शौचं
अद्रोहो नाती-मनीता
भवन्ति संपदं दैविम
अभिजातस्य भरता।
Thus, if this is good, then my question to people is - what is the need of proselytism? Can't people just tend to be good and spiritual rather than invoking a new God at every available opportunity? We have already divided the landmass of the world into various countries, countries into states, states into districts, districts into talukas (From the Indian PoV - perhaps translatable into counties?) and so on. We have divided water bodies, resources, even air (In times of war, we do talk of this country's airspace and that country's airspace.) We have divided people, into classes, and now, even God among different religions. Such is the arrogance of the human race.
And for the demoniac:
४
दम्भो दर्पो ’भिमानस च
क्रोधः परुस्यम एव च
अज्नानाम काभिजतस्य
पर्थ संपदं असुरिम
"Pride, arrogance, conceit, anger, harshness and ignorance—these qualities belong to those of demoniac nature, O son of Pritha."
These are the attributes we see in the religion of the proselytizers.. "you believe in false Gods, you worship idols, you worship animals,.. forget that and look at our God".As far as proselytism is carried out by force, it is certain that that will be opposed by a country's people. What may pull wool over their eyes is when people start converting by allurement.
So, as far as charities given by the foreign missionaries practicing proselytism is concerned:
Ch. 17
२०
दताव्यम इति यद् दानं
दीयते ’नुपकरिने
देस काले च पत्र च
ताड़ दानं सात्त्विकं स्म्र्तम।
"Charity given out of duty, without expectation of return, at the proper time and place, and to a worthy person is considered to be in the mode of goodness."
२१यात तू प्रत्युपकारार्थं
फलं उद्दिस्य व पुनः
दीयते च परिक्लिस्तम
ताड़ दानं राजसं स्म्र्तम।
"But charity performed with the expectation of some return, or with a desire for fruitive results, or in a grudging mood, is said to be charity in the mode of passion."
२२अदेसा-काले यद् दानं
अपत्रेभ्यास च दीयते
असत-कृतं अवज्नतम
तट तामसं उदाह्र्तम।
"And charity performed at an impure place, at an improper time, to unworthy persons, or without proper attention and respect is said to be in the mode of ignorance."
Take a stand. Protect your land from poachers. It is indeed true that God protects those who protect themselves. But in times like these, it is us too who have to protect God (deities.. to be specific). For without our worship, they will fade into the oblivion. Besides.. I also see it fit to oppose proselytism for the reason mentioned at the start.. that other countries can't get a say in another's sovereignty.
