How can you teach sinners if you refuse to associate with them?
God blessed us with the Internet. That way, their diseases are useless against us.
Let them associate with each other like in Romans. That should clear up the problem - eventually.
Refusing to ADVOCATE is not the same as refusing to ASSOCIATE.
If you wish to "associate" with homosexuals in this culture and political climate, they will universally insist that you "advocate" for them also.
They are truly "those who are not for us are against us," activists.
