A big reason why my invites to join ACLU always go into the trash

I'm willing to help the ACLU on a very limited case-specific basis--assuming I agree with the argument in that particular case. But I will not support the organization as a whole. They are wrong more often than they are right.

I'm no longer surprised by the rationalizations used to restrict our rights.
1st, 2nd, 4th, 10th, 14th or any other part of the Constitution are all easily ignored by the Congress and the Courts. After all, it's a living document you know, full of penumbras.
What a load of crap.

The ACLU's a Liberal organization pretending to be a Civil Rights organization.

I've read that the ACLU was founded mostly if not entirely by communists, for the purpose of defending communists who had been charged with crimes. If this is so, they've not been in favor of American values since the beginning, and any Constitutional principle they argue for in a particular case is for the purpose of advancing a leftist agenda under the facts they were working with. If under different facts the same principle would not advance the leftist agenda, they will argue against it.

Civilian ownership of firearms is NEVER an element of a leftist program, hence the uniform refusal to support Second Amendment principles. Speech which advances, promotes or otherwise supports leftist principles or programs must always be protected, but speech which opposes such principles will be opposed - hence the variable arguments the ACLU is willing to advance under the First Amendment.
