Free speech is not absolute, there are exceptions. And the government can’t really stop hate speech until it crosses a certain threshold. Also, the fictional gay couple in the case in question was literally denied a platform and your argument has no internal logic, so I’m really not sure what you’re trying to say. Saying you can’t discriminate against gay people is not the same as saying you should be forced to build websites for Nazis. To argue otherwise is disingenuous.
