This is 4chan we're talking about. They crap on everything and everything in there, you should probably stay far away from there if you want to talk about anything you love without getting a corrupted response. Its for the best if you ignore them.
That being said, while the FE community has been rather poor lately, its nowhere near as bad as some other fandoms I've seen, and its due mostly to the severe Gatekeeping some veteran fans spout, mostly against casual mode and other changes made to encourage newcomers. So its suffering from a different problem entirely than the Sonic fandom is.
If you still feel animosity about Conquest, than its because of 4chan, rather than the game existing.
