No! It certainly won't stop the gobsites in The ROI and nor will it stop what's already been passed in Nordieland! Which illustrates the more bankruptcy of those involved in bringing these laws in!
BTW even though he will see straight through it, there's no way Mickey Gee Higgins will refuse to sign it into law, as if he refers it to the council of state and subsequently The Supreme Court, if it's found constitutional than at that point, it can never be challenged there again!
Rather frighteningly, of all the 1000s of men (lesbian acts were never criminalized thanks to queen Vic being unable to imagine such acts could occur!) who were convicted in consenting adult male to adult male sexual acts in The UK, when obscenely, such acts were crimes, only Alan Turing, the incredible man who according to Churchill (a man BTW, who as a younger man, won the sort of legal case that the Great Oscar Wilde did not) did more to win the Second world war than anybody else by breaking the Enigma Code and undoubtedly saved millions of lives, was ever pardoned and that was quite recently!
