All of these appeals to 'gut instinct' and 'what the heart says' are ridiculous self-righteous justifications for a revolting cynicism.
It doesn't wash, I'm afraid, even if you try and counter it with token would-be rationality. The 'arguments' against this mosque being built that have been put forth in this thread basically amount to this:
'Even if I can see reason, put forth by others, I'm basically knowingly ignoring it to indulge in deeper hatred, anger, cynicism and, frankly, Islamophobia, and because I am calling all of these prejudices "gut instinct" or "what my heart says", that somehow makes it alright, even if I self-glorifyingly acknowledge it as a "bad attitude", because at least it's honest.'
It's a very backward way of thinking, actually.
