Yes, you can say things here without repercussions as long as you follow the rules. Someone here says you're lying, so what. You haven't lost your reputation, job, or anything else in real life. If you can't handle pushback then walk away.
I have no interest in arguments that attack persons, and that means other persons too, not just me. That is how juveniles argue in the schoolyard - “you're stupid so I don't care what you have to say” which often escalates into fistfights. A childish waste of time that evades but does not resolve arguments. Throw as many as you like but they all go to my trash.
If someone is really unqualified then you should be competent enough to take apart the arguments. When you addressed the argument, like when you pointed out the irreproducibility of the associative learning experiment, I took that seriously and responded as such. I was willing to concede Gagliano may be wrong. But notice how the NIH paper refuted her work without calling her unqualified or a kook or fraud. Being wrong in science is an expected part of the job and not definite proof for incompetence. So I just disproved your assumption that I have no respect for the truth.
