I wanted to clarify that a person can do two things simultaneously:

1. Get behind the club by shouting on from the stands, buying things from the shop, interacting with their socials etc.
2. Criticise the manager on an niche internet forum of about 200 people.

Doing the second thing doesn't affect the first in the slightest.

I'm not sure where this idea has come from that questioning the managers tactics on an internet forum means you are not getting behind the club you love. If anything, its because you love the club that you do it.

Now... The stadium boo boys. That's another matter entirely. They do suck the life out of the place.
