Laser is light amplification by stimulated emission of radiation. Fresnel lens doesn't amplify light it focuses it. It is not stimulated, it is just passive component.
This is true, but I don't think many people think of laser as anything other than "dangerous light." That's how I used it. Colloquial meanings can be frustrating when they clash with the technical meaning, but trying to fight them is typically futile.

"Many people" have taken first year physics, or at least read a wikipedia article, and understand that the defining feature of a laser is its coherence.
But, sure. It's 2020. We live in a post-factual society, words have no meaning and it's impossible to know anything. Why resist?
