Facebook Etiquette Question

[kairos12]

How do you feel about getting in a flame war on Facebook on someone else's page, not with the author of the page, but with someone who commented on that page?

1. I feel it's rude

and stupid.

2. I feel like ignoring it.

3. it sounds absolutely ridiculous

but then, most fb shit does

4. I see no upside

to doing so. Opinions will not be changed and in the end why bother.
