Is gene-editing human embryos ethical?

Round 1

I am pro lgbt marriage. Everyone has the right to get married as long as they can consent. In fact. Poly marriage should be a thing. The government should not be able to dictate weather or not somebody gets married to only one person or whatever gender. Love is love. Why should people who have nothing to do with the lgbt relationship get involved?

You hear about clinics editing embryos to avoid genetic disease, and that sounds fine at first. But then it slides toward picking eye color or height. That feels wrong, like redesigning people before they are born. I can't really explain it, but my gut says no.
