Totally true, conservatives are against abortion, gay marriage, homosexualizing the military, open borders, closing border controls and the INS, homosexual adoption, polygamy and pedophilia openly advertising heroin and porn, and so many of the other things that libertarians were formed to promote and fight for.
If you are conservative, libertarians are the enemy, if you are a leftist, then they are your ally.
Only if you ignore the huge and fundamental areas of agreement between liberals and conservatives — some of which I just listed and which you will dishonestly ignore.
