Yes, Xiao Xin is a child who is sometimes rude, sometimes lewd and sometimes even shameless. But Xiao Xin is a kind little man. He will protect his mother and beloved sister. After watching hundreds of episodes, Xiao Xin hardly cried except for a few episodes. In one episode, when his mother was pregnant, he thought her mother was dying of illness and held her in his arms and cried.
Generally speaking, I don't think "Crayon Shinchan" is actually an animated work that destroys the three views, but it is worth mentioning that this animated work does have a certain impact on people's thinking.
On the positive side, the audience can feel some local customs, certain etiquette knowledge, family harmony and happiness in Japan and so on. The downside is that both animation and comics keep a balance between comedy and reality. Once the balance is broken in animation, it will have a negative impact. If you can't tell humor from animation, it's easy to be misunderstood.
So if you are an old slick, you can fully consider the content of animation and learn from each other's strengths, then in fact, crayon Shinchan is not established in "destroying the three views".
