There is no principle here. The zealots are not claiming that we must be tolerant towards all -- that is a principle most could agree with.
No, they are instead claiming we must embrace the things they love, and hate -- and persecute -- the things they hate.
This is not "tolerance." This is, at best, simply the replacement of one set of bigotries and hatreds with the left's favored set of bigotries and hatreds.
