Don't think anyone is okay with child abuse, the comic just hasn't shown anything yet except for him being unkempt and alone for long.
As long as there is not much to comment on yet, people will usually not adress it.
in this case it has been shown. the child abuse in question is neglect. the landlord pretty much stated that the kid is there often enough to know exactly who the kid was and what was going on.
Nothing except him standing and being mentioned to being alone alot has been shown. The kid looking unkempt can have multiple issues that do NOT have to root in abusive parenting. I have seen a few stories like that before.
And again, as long as the abuse is NOT shown and the focus of the chapter, people will simply not adress it since it doesn't matter yet. Comments will mainly be about what a chapter focuses on. The neglect of the kid was not the focus, hence nobody has commented on it. This will certainly change if the author bothers showing his neglect more instead of using it just as a plot device to make a scene or situation happen (which is all it is so far, they even jumped right into a comedic mood with the rest of the chapter).
Think of it like this:
It's like an introduction of a character being homeless while the actual chapter is about him getting involved with the mafia and having to run away from them. Commenting on the homeless issue is simply NOT gonna be the notworthy aspect of the chapter. XD
got rejected by love, tries to avoid it, finds a kid whom is not getting the best life so switches to giving love to the kid to fill the void. truthfully if he isn't asking for anything it is fine. like sometimes you want to help kids because of the situation. if he didn't make the comment on the kid being a looker and that he wished he was the same age as the kid than the whole groomer nature would be swept under the rug. i wonder if the mother learns about this. also why is everyone okay with random child abuse?
