I'm answering these together as the reponse intertwines.
If you offend someone by saying something hateful, then it rightfully constitutes as hate speech in a rhetorical form, however, where equality laws are concerned, hate speech is much more than a rhetoric, its a tool of persecution, used by one group against another, and for irrational reasoning. Its hate in a pure form. Thats not to undermind the impact on individuals mind you, who suffer hate speech in a more isolated way. If for example someone is being bullied at school for no other reason than they wear glasses, and have a sinewy build which someone uses to target them as a 'geek', true or not, that's hate speech which has the power to cause real harm, but does not have the same scope of harm that can result from that rhetoric.
In regards to the question of blasphemy, i posted in my first entrance to the thread, that not only is the right to freedom of speech involved, but that its also about freedom of religion, so shouldn't ever be silenced just because someone happens to take an offence to someone else criticising or insulting their religion. Protecting GOD's from being insulted is basically ANTI-anti-religious (as you effectively force non-believers into honouring a rule applicable to only faith groups).
Its an absurdity, pure and simple, that the league of arab nations think there can be any plausible chance of 'free countries' bowing down to their wishes, to respect their GOD, basically. There is no worthy cause for restricting blasphemy, as it does not constitute as an attack on any group, its a criticism at most. Racism and homophobia are worth protecting against, they ARE an attack on people (which causes psychological and physical consequences).
As far as force goes, it does matter. It doesn't have to be physical though. If someone says in this country on national tv, 'i think homosexuality is an abomination and should be criminalised, becuase gay people are just wrong', THAT is perfectly acceptable. Its somebody giving their opinion, and they are allowed to do so in a nation that respects freedom of speech. If however, someone says 'i think fags should be locked up because they're just wrong', then that rhetoric will be considered hate speech, because the term 'fags' shows the sentimental 'force' that such a person shows towards gay people, a pure hate. What good country wants to protect hate? To do so, under the guise of free speech, is actually taking a liberty with your rights, to no good end either. It only serves the haters.
