In both cases, I would consider it a good idea to watch/read, simply for the fact that it comes from someone who knows what they're talking about, because they're experienced with the other side.
I would certainly take the word of a former christian, or of someone who used to work at PP, over the word of someone who has never done either.
And don't act like any documentaries that come from SJWs are "even-handed" and "objective". 'The Hunting Ground', a highly biased and thoroughly debunked documentary, is still celebrated, and allowed on Netflix, while 'The Red Pill', a documentary that actually IS objective and even-handed, is lambasted as misogynistic hate speech, and Netflix refuses to show it.
The left /hates/ even-handedness, or what they refer to as "both-sides-ism".
