To be fair, the club (and the Trust) already does a fair amount of promotion of mens' mental health and suicide prevention. It would be nice to be in a position where we could turn down a chunk of money for sponsorship, but we aren't a Hearts (or a Barcelona) and don't have that luxury.
(I also have doubts about the effectiveness of shirt sponsorship, but that's a different debate - I can safely say, however, I have never used any of the products or services of any of our shirt sponsors ever).
There's certainly a discussion to be had about beer or gambling sponsors, but that is a wider social issue. I'm a believer that education and awareness is always much more effective than banning things.
