Hate groups are (and should be) legal (just like "hate speech") until and unless their members, you know, actually break the law.

We don't believe in guilt by association in the USA, and freedom of association is constitutionally protected.

> ... actually break the law.

Ahhh. Kind of thought they had, as it seems like a case of (digital) stalking and harassment, clearly targetting a group of people based upon their LGBTQ status and religious affiliation.

No, trafficking in personal data is largely still legal in the US.

Being a hate group isn't illegal.
