I think you perhaps misunderstand...we all have fears anyone laughing at mine isn't funny to me, but I can respect that me jumping 10ft in the air over a spider is probably pretty funny to others... so in a manner it somewhat becomes quite funny.
I'll then proceed to deal with the spider etc as I'm fortunate enough to not be cripplingly terrified of them... (UK ones).
So laughing at others fears if they have the ability to get away from the fear is funny... again, I must reiterate, I would not push the phobia by tricking someone into facing it, nor do I find someone bursting into tears over something amusing.... but having a friend of mine leap into the air flailing his arms around shouting "WHAT THE **** WAS THAT!!?" then running off about 10 metres from a toilet block in a foreign land when some sort of large flying insect was disturbed by his entrance was perhaps something that brought me close to dying from laughter...
Another scenario, we have some hanging hessian sacks over a doorway and I walked through them one morning sorted a bunch of bits turned back to walk through them again and witnessed the largest UK spider I've ever seen. No one else was awake yet and the inlaws were round, so I caught it in a pot and put a cover over it to show everyone as no one would have believed me... My FIL came down, I showed him, then we were chatting and unbeknownst to me my wife came down... intrigued by a random ill placed pot... I was sitting there and heard a huge screech! Got to admit, I laughed.
