Pretty fair summary, I'd say, although I could perhaps think of another to add to your list.
It's not the opinions that worry me, although I think some people do take up certain positions just to be contrary, but it's the style and way -often rather nasty - in which those opinions are expressed.
FWIW I do think Ramirez needs to produce more next season, but some people here do seem prepared to write off the investment very quickly. Pretty short term thinking, and if it were applied in their place of employment would lead to appalling staff turnover, with all that implies.
