Things never post on your blog !!!
1. about race
: Do not post about encouraging violence about race
2. about religion
: We should respect a different religion and we have no right
to criticize other religion
3. Gender

there're still too many comments
degrade women in some countries,
and some man doesn't feel guilty.
