There are reasons to use the same arguments against a character you don’t like. It’s to prove a point. I can’t speak for the original poster, but for me, it’s not even not liking Ninten. It’s just not liking the fact that people request an actual clone and then complain about characters that do play differently just because they have a sword.
And I understand the second paragraph, except I think the whole point of original post wasn’t to poke fun. It was to prove a point (I think) and you can see how they’re trying to do that. ‘You act like this about sword fighters, but then go and request actual clones’. Like I said, it could’ve been said differently, but the point they were trying to make is still right.
Making an argument that doesn't make sense doesn't make you smarter than other people who use it, if anything it makes you just as wrong. And it just serves to upset people who see the argument for what it is.
And that's even if you buy into the altruistic intentions, and not that it's just a thinly-veiled attack on a fanbase.
The “point” is closer to Lucina is more dissimilar to Chrom than Ninten could ever be to Ness. They get angry over blue hair, but ask for identical characters.
Also yeah I have to go soon and can’t keep talking about this-
Courtroom no. 2
There are much more respectful ways to make that point, which would lead to actual debate over the matter. For one, I'd argue (like CJBrine and others have attempted) that similarities between Ninten and Ness are overstated. And also, and I can't stress this enough,
you can't just take the fanbase of any character you dislike and pretend they're all and only FE haters. That's called a strawman. For all you know Ninten fans are actually sympathetic to FE fans as they too are constantly refuting the notion that their character is redundant.
The point being, we can have civil debate over Ninten. I, for one, would welcome the opportunity to at least try to convince people on Ninten's potential, if not his chances. But that's not how you start a civil debate. That's flaming. It shouldn't be treated as anything but, no matter if you like the character, the franchise, or the person doing the flaming.
