I am late to this party, I shall add my 2 cents.
Thanks for watching that christian BS video so we don't have to. Apparently it's much easier to debunk than I thought it was.
Wanting to not follow what one considers "NPC"s is something an NPC does (14:15), some things are hated by a majority of people and some things are not, but the truth is that the reason that girl got hate comments was because her following was anti-christian and they felt betrayed by her choice.
So she's a typical self-righteous christian then. A normal person who has a large following and leaves a path or religion usually deletes her previous account/page and creates a new one to represent her new path. christians feel entitled to just use the same account and just change the content because they arrogantly think their followers were "led astray" and want to preach to them and get them to become christians. This in turn makes their previous followers feel betrayed, as you said. This happened with Steven Banciarcz and many others, who just felt entitled to preach to their previous following instead of focusing on their new path and leaving their previous followers alone.
Another give away is most people when they leave something they just focus on the new thing, not create a video/write a book titled "from new age to jesus" or "deceived no more" or other crap like that. Only christians do that.
Polls show that there are a lot more former christians who leave christianity than those non-christians who convert to christianity, as christianity is losing followers fast. How many Zevists, New agers or Wiccans make videos titled for example "from Christianity to Zevism" and describe how horrible christianity was and how great they are now? Literally zero. Why? Because we're not pushy, preachy assholes like most christians are.
If it's true, then I would question the OP how she finds her "well-spoken" or praises her, because she has a shitty, self-righteous personality just like most christians who feel the need to preach to us because they feel we're "lost". That's why most non-christians hate christians.
