Isn't it odd how relationships and situations that were commonly accepted and encouraged 200 years ago are completely unacceptable now? And vice versa.
For example, a relationship with a close friends family member would have not only been regularly accepted, but also highly encouraged in the past. Now the attitude regularly seems to be "how dare you think my family member is attractive."
And the inverse, a couple hundred years ago having relationships with someone outside your religion or ethnic group was not only frowned upon, but was at times met with violence. Now it's not only common place, it's encouraged to embrace people of different backgrounds.
It's odd some things that used to be ok no longer are, and other things that used to be taboo are more than ok.
People and the world are weird.
