That couldn't be more wrong
Cartoons have different flavors in them that make it even better than anime which just has the same plain old flavor. When I was little, I used to make up new episodes of cartoons. When it's the same episode over and over again, it just sticks with you and you miss the fun of making up another episode yourself. Also, cartoons can boost your self esteem because you don't have to be "cute" to be a good character. Anime lowers your self esteem because the characters have unrealistically "cute" looks that make people think they have to look that way to make everyone like them. Anime all looks the same. The same plot with different characters. And anime is just 30 minutes of "entertainment." Cartoons offer an entire path of experience. Also anime has the dark moments wayyyy too visible and you miss the fun of trying to look for them (or even making them up) yourself.
