There will always be differences between people, you can't make everyone being the same and having the same opinion. What can be changed, at least, is how you or anyone else say his opinion about a certain map or mapper. Sure, you can say you don't like X map, explaining why and how it could be better, building up an healthy conversation. But when you just say you don't like all osu!catch specific map/mappers because they are just easys or they only map easy ones is inappropriate and spreads toxic. This will though never change as long as the community only has 10 actively speaking people and no one helps the mappers to improve their maps. All of us needs to do something in order to improve this, tell to these people to stop talking like that or shift the conversation into a better one, if that not helps, use report.
Well, thats just my own opinion. Which obviously, might differ from someone else's.
