The words glory and incest do not convey the meaning for which you applied them.
The word glory has religious roots. It basically means that glowing saint's halo. So gloryfication is likening something to something holy. What you described is many things, but not gloryfication. Gloryfication is the extra step to make something good even more splendid. It is not getting praise, it is getting very great praise. Mere praise is not enough to invoke glory. It is not treating something as being better as it really is, it is treating something already splendid as even more splendid.
Incest is a neutral word in regard to consent. It specifies blood relation. Cousin marriage is incest. About 10% of all marriages world wide are incest marriages. The statistics is a bit distorted by some regions having up to 50% and other near 0%. If a blood relative commits sexual abuse, you get incest on top, but you can't use them as synonyms.
to cause to be or treat as being more splendid, excellent, etc., than would normally be considered.
to honor with praise, admiration, or worship; extol.
sexual intercourse between closely related persons.
the crime of sexual intercourse, cohabitation, or marriage between persons within the degrees of consanguinity or affinity wherein marriage is legally forbidden.
very great praise, honor, or distinction bestowed by common consent; renown.
adoring praise or worshipful thanksgiving.
the splendor and bliss of heaven; heaven.
a ring, circle, or surrounding radiance of light represented about the head or the whole figure of a sacred person, as Christ or a saint; a halo, nimbus, or aureole.

That commentor blocked me, after dropping some insults.
The usage of words was and is incorrect, no matter if someone gets angry about being corrected about it. If a discussion is about "incest", but someone means "incestual rape", misunderstandings will occur. Same if something is called "glorification", but meant is "trivialization and objectification".
I hope people like that do not enjoy killing murder death games, because according to such logic that would mean their brain is rotten by all that murder gloryfication that is happening in every rpg, shooter, platformer, right down to harmless Mario games where it is ok to kill little creatures by stomping them to death. One is even awarded points and high scores for such activtiy. (Should the post be edited or deleted, there were ad hominems against basically all people that might play questionable games, because their brains got rotten by doing that.)
