The title does not say Bangalore is not a 'real name'. That is your intepretation, presumably to justify your argument.
> Respect starts by not forcing pronunciation on foreign languages
Not forcing anything, it was posted as informational. The tone in the link or my comments is not forceful. Your own tone, however? Again, framed justification.

Not just Kannada, all of the above mapping services "actually" recognise Bangalore as Bengaluru. But, if you don't want to do that or take offence to a perspective that differs from yours, that is your prerogative.
