Keli, I pretty well ignored that sort of thing in grade school.

When those "idiots" realize they can't bait you, they soon realize it isn't very funny and is actually pretty boring.

It does take a lot of conviction to NOT strike out at people, but it is WELL worth it in the end. Who knows, some of THEM might respect you for it. Stranger things in life have happened.

Short of actual physical abuse, it is ALWAYS safer to not respond, OR even more irritating to those who attempt it, you CAN respond with this simple phrase

Thank you for your concern/opinion/thought(s) on the matter. I will think it through

Of course you are smiling that little "Mona Lisa" smile!
