I already mentioned that shoehorning criticism of religion into conversations that were unrelated came across as bitter and myopic. Your point was, essentially, that a lot of people are bitter towards Christianity, which is implied by my own observation. If you have nothing to add beyond restating what was already said by the person to whom you are replying, then I would suggest saving yourself the time in the future and just clicking the up arrow. Or doing literally nothing. Either of those are fine options.
