Hate is such an overused word these days. It's okay to disagree with people and stay friends so long as you choose friends who respect your opinion.
And even people you don't know, and organisations too, political, religious or whatever, If you disagree with what they're doing, say so, politely and respectfully. If they are mature adults they will thank you for your feedback, whether they take it on board or not. If they are immature babies they will accuse you of a hate crime or something equally ridiculous. We live in strange times.
