Good joke 
Conservative doesn't mean we blindly believe everything that every Republican politician says.
It means we believe in freedom of speech, freedom of association, the right to bear arms, capitalism and free markets, limited government, and [in my case] setting up financial incentives to give one-way tickets home to people whose ancestry is in the developing world.
And that's because I am a very humane person. After all, White people - and straight White male conservatives in particular - are evil racist bigots. So why subject the poor non-Whites to all this racism and oppression? The humane thing to do would be to close all borders immediately, and financially assist the poor, oppressed non-Whites to be sent back to the developing world.
Just think about all the evil racism and microaggressions these poor people need to experience at the hands of evil, rotten Whites on a daily basis. Is that fair to you? As a conservative, I always want to do the humane thing. Hence my views on immigration. White people clearly can't stop oppressing poor non-Whites, which is why I want all non-White immigration into the USA to end now.
