True there're repercussions to everything, however as a society we decide what is and what isn't an appropriate repercussion to every transgression, and for a long time now as a society we haven't accepted these sorts of repercussions for people expressing opinions that others find offensive and for bloody good reason!
Nobody, I repeat nobody, is saying that their aren't or should not be repercussions for freedom of speech and expression, we're saying that these repercussions (ruining peoples lives and threatening their livelihoods) are bad repercussions that go way to far.
And those young gay people would be a lot worse off right now if the people that offended the sensibilities of the majority by coming out in support of their rights were all treated in the manner that you are supporting that Folau be treated in!
We have Freedom of Speech and Freedom of Expression for a very important reason, to protect those with minority opinions! And though your opinion my be a majority opinion at the moment it almost certainly will not be forever, so if you get rid of those protections now there's nothing stopping future generations from doing what you are supporting being done to Folau for his opinions to people that share your opinions in the future.
