quite the opposite actually :p you can play all genres on an electric guitar, literally actually since you just have to get the right effects for the job, only difference is that it won't sound as good as the original instrument

I think it's better to start on an acoustic guitar because the neck is wider which gives you more space for your fingers and you need more effort to play correctly since it's a little bit harder, when you switch to electric guitar it's much easier (if you can get used to the smaller space between the strings)
