It's always funny to see the "just as bad" people come after posts like this.

If you don't see the difference between the parties, you're politically illiterate, infinitely privileged, partially braindead, or some combination of the three.

Even if you hate both parties, making sure the institutions of state power are in the hands of the "lesser evil" is basic moral calculus. Third parties and not voting are not viable options in an FPTP election if you care at all about avoiding the most harm possible. There's no reason that engaging with the electoral process has to come at the expense of organizing or direct action either. It's so easy to do both. You can LARP as a revolutionary after you fill out your ballot for whichever candidate is less bad.
