The Unionist parties are not sects. They are political organisations. It is not sectarian to detect political organisations. I detest the Tory party (have done all my life) and I detest the BNP. I detest Trump's version of Republicanism. I detest UKIP. I detest Likud. I do not detest individual supporters of any of those organisations (I tend to avoid 'em, or at least keep their politics at arm's length), though I may regard them as wrong-headed and delusional. On your side there are people who detest Hamas and Corbyn's version of Labour. You're not the number one fan of either yourself. Arguing for policies detrimental to one class or ethnic group in your country is what is sectarian, not doing your damnedest to oppose the policies of their political parties. That's called democracy, Keith.
