If pedophilia is included as a sexual orientation it can cause backlash to laws intended to end discrimination based on sexual orientation. The gay community, which Cantor is a part of, is especially threatened by this.

lolwut?

The existence of laws against discrimination for sexual orientation is its own proof that there is no social threat[*] to people based on sexual orientation (gays and lesbians at least, which is what those laws were really originally written about.) Only places tolerant of differences in sexual orientation would even pass such laws in the first place.








[*] Individual threats from individual assholes may continue, certainly, but they are impossible to legislate out of existence.
