yeah i wondered why they didn't say 'gravity is a type of electromagnetism' or something rather than 'gravity doesn't exist'
but then i guess people say if it is a type of electomagnetism why is it not effected by any electric or magnetic charge? so it's probably better for them to leave it open
Your right, the next problem with that line of reasoning is that like charges repel. Lets say we have a situation where 3 bodies (A, B, C) are attracting themselves under the influence of gravity. If they want to say gravity is an electromagnetic effect, they have a problem. If A has a positive charge, then for B to be attracted it must have a negative charge, but where does that leave C? There is no way to reproduce gravitational attraction with electric charge with only 2 charges.
So lets just pretend there is a 3rd eletrical charge (that no experiment has ever even hinted at). OK that fixed the 3 bodies problem, but it won't work for a 4 bodies.
Ultimately you would need a new charge for each potential body, Now consider a mole of hydrogen gas (about 1 liter), you would need 1 mole of new charges! So I often tell these guys their ideas make sense except for the fact that they are missing 10^23 charges. This dog don't hunt.
