I think you're missing the distinction between what is legal and what is right. I will cheerfully agree that the "expert" attempt to marginalize those who disagree with them politically is legal, and any attempt to legally prohibit it would have worse consequences (not least of which, the experts would use new laws as a weapon against their enemies rather than the other way around.) I will not, however, grant that it is
right.
> Well, as any form of full or partial freedom-restriction works both ways, the thinking is that social groups with less power deserve more protection. Obviously, no one like to be marginalized in any way -- even the more powerful members of society -- but if someone must be hurt, we prefer it to be a group that will suffer less real damage.
Bit of a tangent, but if you deliberately wanted to create furious opposition to your policies there's no better way than to put unequal protection front and center. "Everybody should be protected from X" is a winning policy. "These strangers over here should be protected from X, but not you" is, to put it charitably, not.
