In what fucking world does political speech not deserve at least as much legal protection as being homosexual?
In any case, you're illustrating my point perfectly - it's all about "businesses have the right to exclude customers" until the customer happens to be someone HN likes, at which point the goalposts move wildly.
Marriage equality was about equal treatment under the law. It was debated and decided and passed. You can’t generalize that to your imagined right to troll Twitter.
The question is: do businesses have the right to reject customers?
If the context is political speech (which is critically important and deserves the most extreme legal protection), HN says “you’re fucked, Jack, business rules!”
If the context is gay marriage (which, saying this as a gay man, is not nearly as fundamentally important as free speech) HN says “fuck those businesses, they can’t kick you out!”
Please debate the actual argument instead of a tired straw man.
