I just had soemone tell me, in their opinion, all pedophiles are gay and covering. What brings people to group things like that? How can you even connect that? This is just a prime example, but why do people associate things they personal;ly do not like with things society is whole heartedly against? Just to make them appear in a bad light, or make their point seem more serious.....?
Why?
Humans do this all the time. We do it in ways without even thinking about it.
How many times have you heard someone refer to "my people". Even when you know that person has at best an obscure genetic heritage with "my people", do not even speak the language of "my people" but continue to associate themselves with that identity solely based on their grandmothers heritage, the color of their skin or whatever else that can be loosely associated.
And it's this mentality that's probably more responsible for human strife than any religion, or lack thereof, or even any political ideology.
Don't be surprised to hear people group others, stereotype them with good or bad qualities, when we so easily throw a label on ourselves and throw ourselves in a group.
edit: But the whole gay equals pedophilia even moves beyond what I just said into a different level of.......ignorance. Hate, as others have mentioned.
