toxic cleaning products
toy or real guns
My list is similar to yours. The cleaning products are not as high on it for me, but would rather go for non toxic 1st.
Guns or weapons (toy or real.)
violent games, books or movies
drugs, cigarettes, and most alcohol (DH and I do not drink it, we do allow guests to bring their own but we don't keep it in the house.)
Bratz dolls. Evil things. There will be none in my house or things like them.
things that are racist, anti Christian or anti Jewish or hateful things in general.
Other then that I am pretty open.
