I never flag anything, besides, it is usually already done, so why bother?
Enforcing the guidelines are the mods territory and I see excessive flagging to be controlling and childishly petty, right up there with those that ask certain people do not answer their Q’s. because they are so immature they cannot tolerate any sort of disagreement without feeling the need to control others expressions, good, bad, or indifferent.
It’s a big sandbox here, easy to take your bucket and shovel somewhere else if you don’t like the corner you find yourself in.
