I hate jelly beans anyway but even so, it wouldn't stop me from buying them if I did. If he wants to spend his own personal money on such things then so be it. He may have gotten that money from his company but it's still his own personal money, it's not like the Jelly Bean brand itself is covered in anti-trans slogans, if so then I would be more pissed off.
There is plenty of arseholes in the world with this view that we should be against
LGBT and everything that comes with it, one more doesn't make a difference. I believe eventually, this will all be a thing of the past.
