As an outsider, It doeesn't look to me like a left vs right issue.

>We, the left, strive for social liberalism, civil equality, freedom of speech,

This seems to hint at the problem. You (the left) conflate freedom and equality, as though they are similar goals that can be achieved through similar means. But often these goals conflict with each other; Trying to achieve one often works against the other. Since we need decent amount of both in a society, maybe we should strive for a balance between the two using a common-sense approach?
