Maybe not so much "supporting it" as becoming resigned to it.
In other words, not doing anything at all to fight it.
Which is what WE should NOT allow to happen.
We probably should have done that when WE were smokers...
But most of us felt guilty about it so we kept our mouths shut and let them do what they did.
I never felt guilty about smoking, except for smoking indoors till our son was 9 -- it shouldn't have taken me that long to see it was affecting him pretty seriously, but I was just going on the fact that I was around cigarette smoke constantly since birth, which didn't affect me nearly as badly as it did him, and with him, it was only my smoke, no other. But I guess it affects everyone differently.
But otherwise, no, no guilt about something I enjoyed; fear of the ultimate outcome of smoking, yes, but no guilt. But I didn't feel like there was anything to be done about being marginalized -- the smoke nazis seemed to be the "cool kids" that everyone wanted to cater to and placate. My experience with "cool kids" in high school was that it was best to just ignore them and hope they ignored me, but object to anything they did? I knew how far that would get me.
I've felt marginalized my whole life, so the experience of it with smoking was nothing new or different.
