yes, but only if the idea stands up to questioning.
just because some theories do doesn't mean all new ideas make sense.
just because some ideas are old doesn't make them wrong. indeed, you have successfully to disprove them in order to make them go away.
but you have to be fairly confident of your insight if you are not especially well informed about your subject-matter and yet hold a strong opinion.
appealing to the authority of a few random websites is not terribly persuasive. there are plenty of theories in cyberspace. if you are going to appeal to authority, i would have thought you could point to something which showed links to peer-reviewed research papers specifically on this topic. perhaps a wikipedia page. something.
there are plenty of ways to attack physics without suggesting that gravity is a form of electrical force.
why is it that almost no trained physicists have adopted the electric universe model. perhaps it is because it isn't a strong theory? maybe it is just a loch ness monster.
