"The arguments of homophobes are easy enough to demolish in the open, using facts and sense. There's no need to drive such arguments underground. Expose them to the light and they wither."A noble sentiment, but not true.
The "arguments of homophobes" have been blasted across North America for at least 60 of the last 75 years; they"withered" when civil laws against hate speech gave people enough leverage to shut up the most egregious hate-mongers.
Think whatever you like, but why should I have to see and read and cringe and confront any homophobic, anti-Semitic, sexist or racist crap shoved into my mailbox, or handed to me on the street, or broadcast on radio or TV or the Internet?
I don't need it, our society doesn't need it.
People have a right to live without hate.
