It doesn't matter if people actively working to deny some groups their equal rights are hateful or not; they could be the most charming people in the world. No one is suggesting jailing the holders of said beliefs because of them. But sending a clear message that some views are downright wrong in our society and are opposed to its core democratic values isn't a "mob mentality", and such a clear message in favor of equality does not lead to unfair discrimination, and certainly not to rounding up people and getting rid of them. All it does is educate people that intolerant views are not tolerated in a free society.
