Your concerns about a majority oppressing a minority are well-founded, but a system where people vote for career politicians don't seem to be moderating this problem - if anything it's exaggerating it.

If you trust the general population to vote a marginalized person into office in order to push legislation which benefits that marginalized community, why wouldn't you trust the general population to pass that legislation directly?

The only explanation I can think of is that you think that professional political representatives will have better ideas than the general population.
