Responsible? He's copped his fair wack.
People were booing solely on the back of a like of a twitter post? Is that every single person that booed him? Again you and everyone opposed to his like are speculating on what he's thinking.
Whether or not you and I don't like that he liked the post is irrelevant, what is relevant is that the over reaction is real - everyone is ready to hang him on his like of a post of someone elses beliefs.
Do we draw and quarter Bachar Houli because he's an islamist? You know because we know that islam in it's endth degree is non accepting of homosexuality, equal right for women etc.?
How about any religious person? Because you know we know in the endth degree just about every religion is non accepting of homosexuality, fornication, drinking, thieving etc.?
Ok to be opposed to anyone who has religious beliefs just as much is to be opposed to atheism or believing in your faith, how about everyone accept that Izzy and Gary are allowed to have an opinion as distasteful as that may be.
