Thamizh Brahmins, at least from the opinions they express and how they are perceived by non-brahmins, are less patriotic towards the 'thamizh' cause. Be it Srilankan thamizh issue or indhi-thinippu issue (a.k.a forcing Hindi on thamizhans by masking it as national language) - they are more willing than non-brahmins to abandon the thamizh cause and align themselves to a more national (read anti-thamizh) view. Karunanidhi, Periyar and Anna Durai claim (much to the disgust of brahmins) that people of this caste are not-thamizh but rather aryans or whatever bleh - and it seems like the pattern of behavior matches those claims. I am not trying to get into 'right' or 'wrong' of the issues here but simply pattern-recognition. So I urge readers to treat it this way.
It is hard to ignore the pattern where a majority of Brahmins are (a) enamoured with Hindi and the status associated with speaking Hindi. Some I know 'vaaya polandhu' paathufy (mouth agape and see) people who speak Hindi fluently and despoly try to talk the language in a bad accent even when there is no need to. Many are proud to say they don't know thamizh but only Hindi; (b) quick to disrespect and lessen the importance of the 'thamizh cause' (as in they think it is not a worthy cause). They are ready to support a hypothetical legislation which adopts hindi as a spoken/written language of the state (even when there is no need to do so now given the dominance of English) at the cost of ignoring thamizh (i.e. they don't care if thamizh becomes extinct as long as learning Hindi puts them at some advantage) ; (c) condemn LTTE, sri lankan tamils without any consideration/debate and urge for non-interference of India in this issue regardless of what SL does to thamizhans there (predominant reason quoted is - it would contradict India's stand on another state - Kashmir) (d) Very quick to 'pooh pooh' and belittle thamizh language's classical status, its history, and its unique tendency to resist (to a decent extent) invasion of its space by other languages. Some non-brahmins may be guilty of all of this but these traits are very common, popular and considered common sense in this caste.
While brahmins are seen as indhi suck-ups, non-brahmins are suspect English boot-lickers. The minuscule few who come to western countries take enormous pride in talking in fake accents and try and behave like a DCBA (desi confused by americans). The single biggest pattern I have noticed here is - regardless of whether they live in India or outside they always teach their kids to say 'mummy' and 'daddy' but not 'appa' and 'amma'. In the late 80s and 90s, funny phrases such as 'daddy thittum' and 'mammi veiyyum' were used by economically backward converted Christians. But these phrases are becoming more and more common now. People in this category always mispronounce 'ள' and 'ழ' and pronounce it as 'ல'. This category, while they respect thamizh, are poor in pronouncing it and mastering it (even the minority brahmins who take interest in thamizh are able to master the language better than them barring a few exceptions).
Needless to say the stereotyping theme was 'caste' and 'language'. And needless to say the truth is usually in some shade of gray and in between the two extremes. But the point of the post was to test (1) How popular is this stereotype is among the set of stereotypes people do w/ caste - is it more prevalent than just me and my group of friends or (2) does one category think the stereotype of the other category rings true (but at the same time feel the stereotype of themselves is untrue :-) )?
