What general commentary is Dr. Seuss making on race and ethnicity

Dr.Seuss made some really racist books based on black people and Chinese, Asian people like back when world war 1 happend he made some racist Chinese ads and stuff like that but since then people had totally forgot about it.

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.

no one should discriminated against because he or she is not from a minority group
