I won't bother directing you to the evidence then.
What evidence is there?
Being an Irish nationalist does not mean he hates everything English.
Not wanting to wear a poppy because he's from a city where civilians from his community were murdered by British soldiers is a fair reason, and is not anti-English.
Not facing the English flag during a national anthem is a bit rude, but an Irish nationalist from Northern Ireland is obviously going to have a very fraught relationship with British symbols and pageantry.
Pro-IRA comments are out of order, but it's not unexpected from a man from a community that is inevitably going to view the fight for Irish unification as a positive and see their actions through rose-tinted glasses.
One man's terrorist is another man's freedom fighter.
He's clearly a bit daft and hasn't helped himself over the years, but I've never seen any comments from him that are specifically anti-English or England, so I'd be interested to see your evidence.
Most of the actions over the years have been rejecting symbols of the British state, which is obviously going to happen when he wants Northern Ireland to unify with the Republic and cease to be under British rule.
The worst I've seen is him being in the Anyone But England camp, but millions of people who are quite happy to be British follow that rule too.
