So silence, in your interesting world, is the same as support? I think silence is silence, and support is support. If your partner decides to quit their job and pursue a new career in the arts or as a nurse, and the must you can muster is to say nothing, I don't call that being supportive. I think you only call it support when you want to criticise someone.

What makes you think her husband doesn’t support her?

I prefer to not publicly shame people for the actions of their family and for their sexual predilections. I prefer to be silent (note - not supportive) unless there is evidence of they themselves doing something wrong.

She campaigned on repugnant points

Did he?

she supports Trump

Does he?

she led ICE

Did he?

and she kills dogs.

Does he?

Sorry to belabour the point, but I think it bears repeating. You know there are families where different members voted different ways? In recent years in my country, a colleague of a friend of mine was the father of someone who became prime minister. The friend divulged that their politics were very far apart, and you know what he did? He said absolutely nothing. So silence doesn't mean agreement, either.
