That seems unnecessarily antagonistic to me, someone started a forum post about it, inviting comments by its very nature. As to how much my opinion matters, that is a very difficult thing to gauge. You'll notice you thought yours was worth sharing, though you did it to belittle to opinion of one person, which seems self emasculating.
To be fair,
@Rado_N didn't tell you to not share your opinion, and he also didn't state that he thought his opinion mattered more than yours...
I don't really see the issue... why does any Utd fan want
more Liverpool fans around them as Liverpool win the PL!?
I'm leaning toward
@PoTMS idea the more I muse upon it...
Feck the lot of them until they are officially no longer the reigning champions.
I like the simple functionality of this. The moment that another team is PL champions, roll down the draw-bridge and let the poor buggers back in, until then, let them gaze longingly from afar at the Cafe.
I have genuinely blocked all Liverpool supporting friends and acquaintances from phone contact - some of them I've known many years. They're not good winners. It's best for them. Just leave 'em to it.
