sadly it looks like that's the only way to force change is to do all you can to make them feel bad about what they did. There is no more constrictive critisim since most figure they will not be heard out. The loudest voice wins reguardless if the disucssion is worth it. And if you don't get your way, just out right attack them till they go away. It swings boath ways for any noble or unnoble cause.
It's noteworthy that there are those that hope to be able to create a rappore where such actions and intelligent disccussion could help created an environment of understanding and acceptance. But like all humans there will always be those that push the boundrays of decency since that line keeps constantly changing in what should be considered decent or indecent. clashing opnions and personal tastes based off either puritant or secular grounds will always find ways to butt heads. I don't see any middle ground anymore. And it looks like when none is reached the yelling attacks begin. =(
