Not that such behaviour is restricted to comics professionals. Recently, after I responded to a post on another blog with no more than the hope of perhaps initiating an interesting discussion, the blogger accused me of just liking to argue. He then stopped following my blog and asked me to stop following his. I was surprised, because the individual had previously lamented the lack of comments his posts usually received, and I thought he'd appreciate my support and attempt to encourage the participation of other commenters.
Reading between the lines, it seems that my lack of enthusiasm for Dr. WHO's gender change had irked him (because he likes the show's direction), and no doubt my views (which I'd previously expressed on his blog and my own) about the way Remainer MPs were trying to sabotage BREXIT didn't sit well with him either. (He's massively anti-Tory.)
Thing is, I didn't vote in the referendum, and had things turned out differently and Brexiteers had tried to sabotage Britain staying in the EU, I'd have been just as against their shenanigans as the other lot. My only stance was that, either way, right or wrong, the majority's wishes should be respected. My nose wasn't put out of joint by him (or anyone) holding the opposite opinion to my own, nor do I jettison people just because they don't share my views on certain issues. However, I get the distinct impression that he's the kind of person who feels insecure about being able to defend his beliefs in a logical, well-reasoned way, and just decided to pull the plug on me.
(Of course, it could be that he simply couldn't be bothered, but why raise a subject and then not be prepared to discuss it? Unless, that is, you believe you're right and don't need to, and only have a blog because you wish to talk at people rather than with them.)
