I've had to think how best to express my thoughts on this before picking the grenade up and pulling the pin..
Neither Jackson nor Folau have committed a crime, or served time in a prison. Based on that I wouldn't have a problem with either being signed. Even if they had, I still wouldn't discount selection based just on that criteria. Everyone makes mistakes and deserves a 2nd chance
The connundrum is that the area of discussion around Folau and Jackson aren't as a result of a "mistake"
They are both being judged on their character, beliefs, personal moral compasses.
Don't forget Jackson's comments were part of a private conversation, it wasn't social media. It was no different to something being said behind closed doors in a changing room. The difference being the private conversation took place on WhatsApp. (I'm presuming all players in all clubs have been reminded of the vulnerability of using digital/internet/phone apps to converse).
Folau is expressing his religious beliefs but at what point do they become offensive to others.
I've personally not been offended by either (i.e. I've not met them personally) so I wouldn't have a problem but in both cases I think I'd have to consider the impact within the club itself, that not only includes the squad but the wider staff.. the office workers, catering staff etc and whether they would have a problem dealing with both on a daily basis
I suspect both would be an unwelcome distraction within the club which is what has come to transpire at London Irish, so as a DoR I wouldn't sign either.
