I mean, in particular, this answer: https://christianity.stackexchange.com/a/59972/25763
My first instinct was to flag it, however, seeing that already 2 ppl have downvoted it before me w/o flaggint it I started wondering if flagging this answer was appropriate.
The answer consists almost solely of a link to a YT video whose purpose seems to be the propagation of a particular sect, as well as attacking Catholicism. I haven't watched the whole video (it's almost 20mins long); so I'm not sure if this video touches the subject of the question; but even if it does it is clear that the primary purpose of this answer is the propagation of the answerer's particular sect.
Is such an answer on-topic here? Is it appropriate for me to flag such answers?
