Why do you think the left keeps them down ?
Conservatives hope that someday these people who want free stuff will realise what that strap is for on the top of their boots. It's for pulling yourself up by the bootstrap.
So you're going to make the completely unprovable (and undisprovable) claim that the "left" race-baits more than the "right," a claim that we know right off the bat that no standard of proof will be good enough to refute, and failure to disprove said undisprovable claim will be considered a victory for you and clear evidence of which side is the "real racists."
Freedom of speech is not freedom from criticism.
