Should I skip Fillers??

I think if the question "should I skip the fillers" comes up my answer will always be: either watch it in its entirety or just don't watch it at all. Fillers do exist for a reason and how can anyone say that certain episodes don't matter at all to the plot when everyone has different definitions of what that truly looks like. Not to mention anime and manga are allowed to exist separately so just because season 2 is not canon in Kuroshituji manga doesn't mean it's useless or "filler". Like 3/4th of Kurpshitsuji season 1 is silly and can be considered filler even though every episode does bring something to the story even if it's just character building. Season two is it's own unique story but that doesn't make it bad just because it's not manga canon, the story for season two was STILL CREATED by the mangaka... If you want strictly the canon manga story then.. read the manga!! Seriously Just watch stuff as it's intended to be watched and if that's irritating to you then you simply don't like the show and have the free will to give up. To me it just sounds like nobody wants to actually watch anime when all we hear about is skipping fillers. Like maybe somethings are just uninteresting to you and your attention span while other things are the opposite.. and that's okay!!
