I used to feel that way, because I thought things like Roe v Wade and other rights were solid. I never dreamed that a woman's right to choose would be threatened again, and I figured if I skipped an election or voted for candidates whose beliefs didn't always align with mine (because "we need a change" or whatever bullshit I told myself) most things would still be fine.
How naive I was. A woman's right to choose is gone in several states, and now they're coming for trans rights and making it illegal to be a drag queen, ffs. If we aren't diligent, what's next? Gay marriage, no-fault divorce, reinstituting legal segregation? A woman's right to vote?
The only way to ensure that all the rights we have fought for as a society remain intact is to vote for the candidates that will continue to protect those rights. Progress may be slow, but it sure as hell beats going backwards.
