Assuming of course...that he's actually reputable.
If it's the "gentleman" that I think you may be referring...he's all over the internet, not just on a Negril FB group page...he also makes "interesting" comments all over the news sites. I'd swear he's trying to go into politics...but everyone's entitled to their opinions.
Imo...I just don't understand his sharing of politics/personal agenda on a tourist based FB page...especially when the facts/reality cannot defend the agenda.
