Rather than respond to the others comments above, I'll just set out a composite summary of what I think my view on the matter is.
Before I do, I'll quickly reprise the facts as I understand them.
THE FACTS.
1. Folau tweeted or retweeted an image which advised various 'groups' of people that they need to repent for their sins in order to be saved by Jesus, and to avoid going to hell. One of the 'groups' was people that he described as "homosexuals".
2. The tweet was criticised, and it became a scandal.
3. The Australian rugby union terminated his employment.
MY TAKE ON IT.
1. As a public figure, as a role model and as an employee, I think that Folau was wrong to post or repost the tweet. Any high profile professional should know that they are a representative of their organisation and that they shouldn't do anything which brings controversy or negative publicity to their employer.
2. I don't know what the contract says, but I don't consider it unreasonable in the circumstances for the employer to sack him.
3. That said I would have been equally happy with people letting it go and just leaving him to blabber on and get ignored and/or laughed at for his views.
4. I don't really see that it's anyone else's business. The guy has made a mistake, and he's been sacked. I don't buy the argument that homosexuals are a minority and need a load of rugger types to stick up for them and stick the oar into Folau on the internet. There is only one Folau, and homosexuals are quite capable of standing up for themselves against him should they feel the need to. The idea of 10,000 internet bashers v Folau does not strike me as a particularly gallant fight in any case.
5. In my opinion, the best thing people can do generally in these type of situations if they really want to get involved is to offer support to ALL of those who may be affected, rather than picking out a bad guy and going wading in with their pitch forks, and to flush out and burn at the stake any other religious types and the like.
6. In my opinion, Folau was likely doing what he thought was right in the name of the religion which he has been brainwashed by. The best course of action I believe would be to try to rehabilitate him and others with similar views, rather than getting angry, and also to consider what approach should be taken to addressing religious 'intolerance' 'ignorance' ? in general, and to bringing it into line with society's wider contemporary views.
7. I find it odd that noone is criticising the bible.
I recognise that other people are entitled to hold, and do hold, other views. Thanks
