Extremist and Hate groups

Since the moment the internet was created there has been one predominant usage, porn (but I'll get to that at another time). But now, a new type of usage is coming up, hate groups and extremist groups. I'm sure many of you have seen things such as 'The Blues Brothers' and other movies, or even in real life, where these groups of people were seen making public rally stands out in public locations and causing a stir. But in these technological ages these groups have taken to the internet to try and spread their messages further and faster.
Now if your like me, you dislike these groups for one main reason, they discriminate. In my younger years I was the target of forms of juvenile discrimination (also known as bullying)and as such I abhor anyone or any group who discriminates against any individual or group just because they don't like a few of them or because they are different. However that is unlikely to be the reason many of you object to hate and extremist groups (the bullying part that is), but I digress.
I recently saw a posting for this group called the 'Australia First Party', so being the inquisitive being I am I sought further information about it. This 'Party' is a hate group which wishes to revert Australia to what they consider to be a purer Australia, in effect a white Australia. This 'party' even goes so far as to support the events that transpired at the Cronulla Beach riots and claim it was a 'revolution' and the 'rebirth of Australian Nationalism'. They even go so far to make claims, in their own report clearly as no news station would report such derogatory, false, slanderous comments, that those who 'fought for Australia' were heroes and that the victims were actually the perpetrators of this event and that they are the true racists. My response to this group is that if you wish to revert to the 'true Australia' then effectively you yourselves need to bugger off as the original inhabitants of Australia were and are the Indigenous Australians, and we white folk are the colonists. Even then if you argue that point that the first fleet is then the 'true Australia' then unless you can trace your roots to being of 100% pure convict/colonist roots, then you yourselves are still not 'pure'. Is it just me or do you my readers see the obvious flaws in this groups points?
Back to the point on hate and extremist groups, is it just me or do there seem to be a lot of small groups all opposed to the same thing? It's like come on, can you obviously not tell that the group just over there is also opposed to the exact same thing? And even sadder, in my opinion, is that a large number of these groups are in countries that preach and celebrate tolerance for others, I'm looking at you America not just us here in Australia. How's this for you America '1st Amendment- Congress may not establish a religion, restrict free speech or press freedom, or deprive citizens of rights to assemble peacefully or petition the government.' i.e everyone has the right to live without oppression, so take that under your hat before you start persecuting those who you feel are of lesser value than yourselves.
