To this last question... Possibly...
Things are changing the world over. People are becoming more open with the exception of a few hot spots, of which we all know and for which to change the spiritual centers of those areas would be foolish no matter what be the respective religion.
Your lead question is not a 'question' of whether you are racist or Christian or not. It is a sane question and more important, a confirmation that you are a human being and sensitive -- rightly so.
Often these old churches have served the purposes for which they were established. Comes now a fresh vortex in each case of the high Spiritual flow fashioning life into forms according to the now new states of awareness.
Do not be alarmed by this, for this is perfectly healthy and is the very edict made and put out to sustain of neutrality in the collective consciousnesses...
This goes beyond mere "tolerance," which is a well outdated ideal. It does not work.
Tell me, would you want someone you love to merely 'tolerate' you...
Of course not !
Souls today 'are' indeed allowing others their alloted worships; therefore, new forms are now being facilitated, working in conjunction with all life and blessed by the Most High.
We are not alone. Fear not, for each of these respective religions are themselves re-fashioning themselves.
You should fear if and only if you did not see these changes you now observe. Do you see?
