I stand corrected, I was referring to HS and Private christian schools combined with that #, and that actually makes it a low number I put out there.
You are British, so your views are from there, and our constitution means shit to you (and also to our Government...lol) but, the Public Schools answer to the Federal government, so any ban like this, would eventually come from that direction I suppose, but anyone trying would certainly lose in court, as it would probably interfere with free speech, freedon of religion, and force someone to exercise their 2nd amendment rights..lol
