I think it's partly a feature of the social media generation. Its so easy to make a comment without really thinking it through or tempering your view by talking to others and the fact that you will probably never find yourself face to face with someone you're insulting loosens inhibitions.
I agree, though, that there is also a sense of entitlement and the fuss over the kit has got ridiculous; if you don't like it, don't buy it. I can't believe the number of photoshopped improvements that I've seen online. Do people really think the club will withdraw it and start again?
Finally, there is a huge misunderstanding of how the playing budget works. There really are people out there who can't understand why we aren't spending £120 million on transfers! I suspect that our wage bill will probably be in the region of £50million, then you have agent fees, travel and accommodation etc on top. I would guess that our actual transfer budget is between £25m and £30m tops.
While I post on this site occasionally, I am not a member of any other social media site so can't debate its role or responsibility. What I do know is that apart from the method of delivery, nothing has or will change when it comes to peoples opinions particularly with regard to the OP.
In my days of the early sixties, standing on the River End terrace, I listened to, sometimes agreeing with, all manner of opinion, abuse and rhetoric. And no doubt the same thing happened when the same gentlemen got to the pub or arrived home for tea, Many landlords and wives would have heard it home game after home game. AND my grandfather used to berate me about who was good and who wasn't worth his wages-and he never went to a match in my memory, even though one of his family was one of the founders of the club.
Why weren't we in the 1st Division after all the money the club has got (forgetting we nearly went out of business in 1957) and why are we selling our best players were just a couple of perennial questions. And when the club introduced green shorts there was many a supporter thought the club had gone too far!
But just as then, today, and because of the close season, opinion about the club, whether literally correct or not, is the opium of the supporter. For instance, I disagree with you about the new kit. It isn't a question of buying it, it is one of the things we are famous for and identifies us too many around the world.
And while most realise the budget and recent financial problems mean the club will not be taking too many risks, there are many out there who see the risk as worth it particularly as many see us as a big club. And I think it rankles with them seeing the team we defeated at Wembley offering silly money for Championship players. And what easier way to express that disappointment, and on a grand scale, than social media. And the more vitriolic, the more attention it gets.
