EDIT: Not just speech, but also other basic rights they have stood for, such as legal representation and rights of the accused.
Their response to reforms of Title IX to restore the rights of the accused was to intentionally lift up the rights of the accusers over and above the rights of the accused. Their statement regarding it dishonestly claimed that they were balancing the scales, whereas anyone who has examined Title IX can easily see it leaves the accused without their constitutional rights to due process.

In a similar theme, they inserted themselves into the confirmation process of Brett Kavanaugh, taking a clear side on the issue instead of standing for principles of legal representation and initial presumption of innocence. [3]
There are other recent articles on continued churning against their prior positions, but unfortunately they are behind a paywall and I do not yet have access to read them. I may be able to find other sources later. [4]

Of course, this is just one case. But it at least shows they're not opposed to defending those they may otherwise disagree with.
It really hasn't been that long since the red scare, where people made comments just like yours, but warning about the dangers of those dirty pinkos towards god-fearing, decent Americans. The first amendment protects us from authoritarians of any political stripe.
Now they pick and choose, and that's not right.
Do I like people with hatred towards their fellow humans? Absolutely not. But I don't think we should muzzle them. One day, that'll come back and bite the rest of us.
Likewise, the EFF needs to focus on the incredibly important missions of keeping software accessible and our privacy paramount. They're getting distracted too.
edit: mistakenly mentioned FSF instead of EFF. I'm clear about the distinction, it was just a mistake. Thanks for pointing it out, mig39.
