US laws don't rule the world. You have gone online to publish your "opinions" to the world at large without the realisation that simply saying it is opinion is not a defence to a case in defamation in Ireland or the UK. It needs to have a factual backing.
The fact that Ryanair was granted orders by US courts disclosing the identities of PPRuNe posters not all to long ago tells me you're taking unnecessary risks to malign a company that has little to do with you all the way in Asia.
Let me tell you, that even in the US, there are exceptions to free speech - and one of those is libel. Where you, due to your agenda, post false information in light of clear evidence to the contrary, you can be sued successfully. There is no freedom to malign another individual or company with falsities.
Courts are not so stupid to see through the "opinion" defence when it's invalid. You may have opinions about crew experience, but you cannot say that a company is acting unlawfully when they are not and that there are improper ties between the airline and the regulator when there are not.
Either you have an agenda or you're trolling, but either way it's annoying.
