As you see, it is about the practice known as "gaslighting" - basically of shifting boundaries, expectations, physical objects, or markers of normality or reality in any form. The purpose is to make the other person doubt their sanity and thereby gain control of that person. In extreme cases, the purpose is to literally drive the other person insane.
Cafe Mom gives gives it a typically sexist twist, by depicting gaslighting as something that "he" does to "her". In reality, women can not only gaslight just as well as men, they can likely do it BETTER. Many of them, anyway.
You will notice that "gaslighting", in one form or another, is exactly the treatment that feminists dish out to non-feminists or men in particular. That is especially true in their various propaganda wars and spin campaigns, as when they warp the meanings of words, shift the goalposts, construct false narratives, reinterpret history, slander people, and so on.
This, among other reasons, is why we must take back control of the language, narrative and discourse from feminism - starting by controlling the definition of "feminism" itself.
