Just for the sake of an open response to this, in the case you’re not actually trolling. Do you really believe this woman does care about the contents of the bible? Or can you see the imo more logical point that she cares about certain political movements not agreeing to the seperation of church and state, leading to actual policy based on a religious book you don’t believe in or agree with?
In that case, where is the need to actually believe in the bible or it’s teachings just to put in the effort of making a sign and protesting? At that point you’re protesting the consequences of a select group of people pushing their religious dogmas on everyone under the veil of politics. Which unfortunately still seems to happen in current times imo.
I agree that religious beliefa are generally on the decline, but that’s not objectively a good or bad thing.
The word virtue unfortunately has too many meanings in this context:
However virtue, if defined as moral excellence, simply does not exist in a fully objective sense. The best definition I can try to personally approximate is to “choose your own actions in such a way as to minimize negative and maximize positive effects on the people they affect”. If I use that definition to reason about the virtuousness of being sexually liberal, I cannot see it as anything other than a virtue, other than hurting others by e.g. being promiscuos within a relationship.
On a more general note, monogamy was not always the norm. Historically a lot of cultures have thrived under polygamy or similar systems. The most well-known one (assuming you’re from North America) are the Mormons, which accept and encourage polygyny.
