Freedom of speech is one thing. Having the intelligence to know when to use it is another
People can THINK what they like but when they take it a step further and DO or SAY something that causes GENUINE mental, physical or emotional harm to others then that has crossed the line for me.
I have emphasised genuine because it really grips my **** when people play the race (or whatever) card when they have no grounds. eg incompetence at work and a superviser/manager takes action only to end up facing an unjustified harrassment charge.
