I agree with this statement.
So in your opinion, at what point does one claiming that they are right and stating that all others are wrong cross the line into intolerance? At what point, in your opinion, does this become bigotry?
I think you hit the nail on the head there. You answered my question before I posted it. Interference in beliefs would be necessary for intolerance.
So where are we drawing the line on interference? Clearly the consensus ITT is that simply telling someone what they believe is wrong isn't being considered interference.
It crosses the line into intolerance once they voice or act upon the idea that others should not be allowed to be different (or that they are lesser humans for being different, I suppose).
