I watch many different teams; mostly Manchester United, who I happen to support.
As to your other question, I haven't seen anybody showing Ten Hag anything that could be called 'constant love' by any reasonable person.
Judging by the rest of your post, I believe I can save us all some time: I could point to his credentials elsewhere, his performance last season, the litany of issues he's dealt with, and the nature of the club.
You'll then cry "no excuses" or some such, committing a fallacy of equivocation because you fail to see the difference between reasons and excuses. You'll probably then argue that any previous achievements weren't really achievements at all, but just the result of a collective mass delusion that only you and a handful of others were wise enough to see through. I imagine you will also throw in some condescending loaded questions and needlessly emotionally charged language in a misguided attempt to make your own opinion seem so obvious that anyone who doesn't share it must be blind, stupid, or both.
I'll politely ignore your tone and set about providing examples that undermine the vaguely salient points you do manage to make. This will annoy and anger you, making you more and more polemic in your responses.
Eventually, simply typing messages on an internet forum won't be enough. The thrill of knowing that what you believe is gospel will drive you to do something more. Something that makes a real difference.
So you get in your car and you drive. You drive until that gnawing feeling that other points of view exist consumes you. Until the importance of your own undeniable absolute truth inflates to fill the void tha has formed in the absence of what was once your own capacity for reason. Maybe you take a ferry? Maybe you take a plane?
It doesn't matter, because ultimately there was only one place your story could end, and one thing you could do to end it.
Enjoy your day, my friend.
