His point was poorly made as it suggests anyone who doesnt evade tax should not be criticised
Hypocritically Sangria will have criticised people who dont evade tax and do want to see an increase in tax.
No one is perfect and some things do feel like 'whataboutery'
Person X says "This person has done A, which is great"
Person Y comes along and says "This person has done B, which isn't great"
That might or might not be true, but what has it got to do with the price of fish. If you're talking about, say, tax and someone mentions something about tax (Positive or negative) then it seems reasonable to respond to or answer the point that was made on the subject.
It's also a reasonable thing for him to opine I feel as 'non-mainstream' things that some people may or may not believe are foisted into conversations which aren't as important (or important at all to them) then it doesn't offer anything useful.
That isn't to say a debate isn't to be had or that it's not important to some people - I took it to mean that it's not important if it's not relevant to that discussion. Quite often it derails the threads and offers nothing to what was said.
Just my 50p worth
I don't mind Rowling myself. She's entitled to her views (Which, from what I've read aren't bonkers and have been wildly mis-represented) - it's a free country and just because someone thinks something or other, should they be hounded to death?
I've got my own views on shit, and if someone wants to persuade me otherwise then fair enough, otherwise fuck off.
