Well no it isn't wrong to hate anything as we all differ on things. However, it is kinda silly to take an entire group of games and immediately associate them with one thing and then decide to hate them. Even further to cherry pick the definition which conveniently leads out so called "hardcore" genres (racers, many shooters, some action games) to keep them out of the pot.
I think what people need to understand that the idea of casual and hardcore is subjective to being with and in the end it eventually turns into elitist versus mainstream versus new entry. We should take pride in being long time gamers but remember that we started off the same way they did buying games that were "safe" from an outside standpoint. And we should also remember that not everyone is going to want to play a 50 hour RPG in 3 days. Sometimes people just want to sit down for 10-20 minutes, bowl a few rounds to relieve stress, and then go watch some TV.
I think it is great that gaming has been able to open up to the masses and when that happens, under capitalism, developers are going to try and support as many people as they can. It brings more games to the industry and more opportunities to have better games. I'm not saying you have to like the things like Gardening Mama or whatever it may be but it is nice to know that the industry is working to expand to bring games out for everyone.
You don't have to like them or even buy them, but know that there are people who do want them. Why should we judge them for what they want to play? There are some elitist gamers who look down on people who call themselves hardcore and play nothing but shooters (I do it sometimes haha). No one likes that feeling. Everyone just wants to know they can enjoy the games they like.
So no it isn't wrong to hate "casual" games, but I do think there should be an understanding and a certain line of respect towards the idea and what it is trying to do. But I'd even further like to break down the ideas of casual and hardcore and just keep gaming as something for everyone with many different options.
