I think there are Tory voters... and then there are "Boris" fans. And it appears that it's the latter who believe any criticism of him (or his party) is simply "bashing" which implies that it's just being done for the sake of "having a pop". Because, in the former group - the Tory voters, especially the traditional ones, there are also those who are critical of the man, whilst still being faithful to the party.
The problem for people like me who are politically 'homeless' is that I can sometimes appreciate the values of both Right and Left. I do believe in 'personal responsibility' (in so far as a person is fit, well and able), at the same time, I also endorse "for the many, not the few" - although I was never a 'Corbynista'.
So I would just like to declare that when I am saying what I think about Johnson, it is not just for the sake of taking an opportunity to "bash" him. I genuinely believe he suffers from Narcissistic Personality Disorder. I think Starmer is an Appeaser. As for Corbyn, I don't quite know what to think about him, except that the LP was riddled with bitter, factional in-fighting under his leadership; and I do believe he failed to grasp sometimes what really mattered to people.
I do however think that condemning Johnson for his appearance - I've heard him called a 'lard-arse' on FB many times - is bashing for the sake of it. In the same way that Corbyn was criticised for the way he dressed. Shaming someone for their weight or appearance is IMO pretty low. And there's plenty to criticise both men for, without stooping to that level.
That's it! Interesting topic...
