As Truth1337 asked, we will be discussing the merits of this argument, as posted by the said member in the Political Outlook thread:

Sexuality: Bisexuality prohibited. Homosexuality allowed, but prohibit pride parades and/or praise of homosexuality.
So, is there really a true difference between the two?

I say no, because all bisexuality is, is being both homosexual and heterosexual. Otherwise no difference.
