"well-known that the left hates discrimination and social inequality"

Complete baloney. The left could care less about discrimination and social inequality. Ask the multi-millionaires in any wealthy neighborhood whom hire illegals for pennies on the dollar. Ask the mega farming and meat enterprises why all the jobs go to illegals. Then ask all of  them which party they contribute to and every one of them will reply with (D)onkey because the (D) party loves to $crew Americans and pander to illegals after getting massive contributions to lower the labor costs back to Great Depression levels!
