Ron Paul supports a wide array of horrendously reactionary policies.
He is for eliminating birth-right citizenship - an extreme right wing position which would make it so that children born in the United States to immigrant parents would be denied citizenship.
He is for eliminating all social programs and government departments - like the Environmental Protection Agency (EPA), Social Security, Medicare, Medicaid, welfare, food stamps, and many other programs which protect working class people, especially racially oppressed groups, from the horrors of unrestrained market capitalism.
He is for overturning Roe v. Wade, which would force women to get abortions in back alley chop shops, where many would die, bleed out, and suffer infections, permanent sterility, and extreme pain and agony.
He is for deporting all immigrants, including expanding attacks on immigrant Muslims living in the United States.
He's against gay marriage and thinks its immoral. He says states should have the "right" to deny people in love the right to marry.
He has had many Neo-Nazis donate to his campaign, and has refused to return donations when this has been exposed. His newsletter has had many white supremacist, racist, sexist, and homophobic comments. He is no friend of working and oppressed people. Ron Paul is an rightwing extremist.
The social function of ideologues like Ron Paul within the capitalist system is to divide working people. If people weren't divided in United States by ideologues like Paul, Bush, Obama, and institutions like the media, schools, etc. - if we actually talked to each other, discussed, debated, weren't segregated by race - then there would be no way that the imperialists could get us to support war and oppression.
That's why they divide us, segregate us, teach us to hate each other over petty reasons, instead of recognising our common humanity: because unity is dangerous to the rich who benefit from all of our suffering. There are so many of us and so few of them - and they are scared of that.
Ron Paul's supposed "anti-imperialism" is just a distraction from his *material support* for imperialism and terror by his efforts to divide and confuse people.
He will never be president. But as a Congressperson and right wing ideologue he is able to promote and vote for all the other policies which divide working people, support imperialism, and further oppression and exploitation.
