I see the Liberal practice of pointing out spelling errors is still alive and well.
Here is a handy guide to know when NOT to point out spelling errors.
1. Never point them out in an article where you also make spelling errors, it is just to easy to use spell check and find out what mistake you might have made.
2.When pointing out these errors make sure the person you are ridiculing has an actual education at least on par with your own or it just looks like you are being an asshat{<not a real word}
3. when choosing to poke fun, make sure you can take it as well as dish it out.
