I understand your personal reasons but consider Trump is on the side of Nazis and others so inclined. The ACLU protects everyone’s rights, rights that I’m sure Trump will try to eliminate if he had half a chance. He’s already threatened the press several times, he favors theocratic thinking and he’s expressed the thought that we don’t need the current justice system.
Even if you hate the use of some rights, if they’re not protected, they’ll be gone for us and the evil will rule.
