I think the way he is always holding his oldest daughter's hand is creepy. What teenage girl would hold her father's hand all the time?
That could be an understatement. The real justification is that they have zero control over their behavior, their contracting of diseases, disproportionate issues with alcohol abuse, narcotic abuse, etc. they are arguing this because without it, the idea of their consequences being a civil right complicates things. Bisexuality works well as an excuse, it also complicates matters because they can’t even tell who is truly homosexual, just like any ordinary person cannot aside from outward behavior, tell if someone is homosexual, bisexual, etc.
