If I become intolerant of people who are intolerant of others, have I become a hypocrite?

No. Supporting human dignity is consistent in that stance. It's not an argument, and thus doesn't stand or fall on mere logic.

No. You have no obligation to tolerate the intolerant. In fact, it would be folly to do so. Karl Popper said it best.

“Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them… We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. We should claim that any movement preaching intolerance places itself outside the law, and we should consider incitement to intolerance and persecution as criminal, in the same way as we should consider incitement to murder, or to kidnapping, or to the revival of the slave trade, as criminal.”

No look up hypocrite. You would be a hypocrite if you were telling others to be tolerant when you were intolerant. Like they say practise what you preach.

You cannot tolerate intolerance,just like you cannot love those that hate you and wish to destroy you.

I asked something similar (although not as well composed) a few days ago. It's already resolved so I'm not asking you to answer it, but I thought some of the responses I got were excellent so you might like to read them?

As long as you show common sense diplomacy in your criticism you are entitled to your opinion so No.

Yes you have, which is what happens every day here in R&S with people angry at others with religious beliefs that they think are exclusive.

Common stuff, sadly.

My mind just exploded

No I think it's called irony.
