I hate to break it to you, but this is a discussion forum and people aren’t always going to like every single character and are allowed to have different opinions.
I'm fine with that, but I at least expect compelling arguments rather than 'haha, she had two non-Dragon types, suck on that!'. But I don't even get that, so at the end of the day, it's people taking time out of their day to express their despise for one character who wasn't even in this episode, all because someone dared to assume Iris might be the mysterious dragon type user. Oh the horror!
Like it or not, Iris is a Dragon type user and has 3 Dragon types (and could easily catch more off-screen).
Besides, this tournament seems so focused on 1 vs 1 fights (maybe there'll be 3 vs 3?), wouldn't be surprised if you didn't even need a team of 6 Pokemon, let alone 6 Dragon types. So Iris is a perfectly legitimate candidate here, so unless you have some nice counterarguments (which you likely don't)...yeah.
..Anyways, it’s not that deep, “you do you” comes across as hateful, so you telling us to not hate on characters is fine, but I’m telling you don’t hate on other members here.
I don't hate you, I don't even know you or anyone else here. What I
do hate is shallow arguments with no substance. So do remember that this is a public forum where people are free to disagree with your opinions, especially with those kinds of arguments.
