Are you publicly critical of others?

On Facebook, on Fluther, in real life? Do you try to be diplomatic with your criticism?

I thought of this question as I live in a community that is having a Christmas party tonight and nowhere on the community’s FB page is there a posting about the time of the party. I posted a q on their page asking what time is the party, and it was seen by 10 people so far (including the page’s admin) and answered by a non-admin. No, I’m not going to criticize them but I’m tempted. Also another q asked by a Jelly here about the weather where the first poster was critical of one of the tags chosen by that OP.

I work for a politician so I am always watching who does what and who is critical of what and who shuts up with their criticism.
