It's quite common to feel afraid of the new: it's an essential survival mechanism. However, just because we get that feeling initially, doesn't mean we should always trust it over a lived experience. People for all time have experienced this feeling when doing something new: riding a bike, driving in a car, and first week of kindergarten. What makes us the hyper adaptable omnivores we are is our ability to become desensitized via repeated exposure to things that aren't real threats.

And of course, sometimes we've gotten complacent and made an error, like lead in gasoline. But that's why we study everything to try to ensure we are improving.

I'm sure cancerous cell lines exist, but could you show that those are used in cultured meats?

Also, did you mean cancerous or carcinogenic? Only the latter therm is about the consequences of eating the thing in question.

That response might add unnecessary stress and complication in your life. I suggest reading or engaging with _why_ you feel this way, beyond the initial reaction. Imagine I felt unduly disgusted by you everytime I interacted with you. Not only is it not prosocial, that kind of overhead leads to bad places (having formerly held on to those beliefs myself).
