Made the edits you've suggested and a few more. Thanks! That said (and I think we agree on this), it doesn't invalidate my argument (see http://en.wikipedia.org/wiki/Tu_quoque http://en.wikipedia.org/wiki/Tu_quoque). The grammatical mistakes I made did distract from the point I was making (ironically demonstrating it all too well). It also wouldn't be good use of my (or my friends') resources to ask others to proofread an HN comment :-)
