first off, im epileptic, however- the type of condition that entails seizures triggered by flashing lights is far less common than you might think- It really isn't even close to an issue

second- i happen to know a guy who has the type of epilepsy that is triggered by flashing lights... when i was playing with a band called tirothi, he was always right up front cheering, and he would have seizures from the camera flashes- but the thing is this, you know when your going to have one... you get a head rush, and a certain scent... you can just look away, or shut your eyes for a second.. it isnt like *flashflash* BLAM

so naw... even though they are rude, it isnt a big enough issue to have to deal with.
