It's a False Dichotomy:

https://en.m.wikipedia.org/wiki/False_dilemma

If you can't argue well for your point, you talk about how bad something else is, with the implication that those are the only two options.

Coal is bad, worse than nuclear. But those are not the only two options.

And when comparing something that uses energy, like recycling, it's not a fair assumption for electric powered things to assume they are using the least efficient method possible, it's just deceptive. Like judging EVs as if the grid was 100% coal. Because even if it was, which it isn't, it won't be for long.

Similarly, added sugar is worse than meat in pretty much every way. Doesn't logically follow that people should eat more meat. It's a type of pass-the-buck whatabout-ism.
