I certainly heard a lot of conspiracy theories at the time, but I didn’t know anyone who believed them. But I don’t and didn’t really hang out with the type of people that believe stuff like that in general. My friends and family are generally empirical evidence people, logical thinkers rather than emotional.
I would assume reasonably and reservedly, rather than jumping the gun. It’s certainly how I responded. Not sure what you really mean to ask though.
If you mean about conspiracy theories, I can pretty much assure they waited to see what was actually the case rather than believe the first thing they heard.
