Russia passed a law in 2013 which outlaws telling children that homosexuals exist.

The statement is false. Russia did pass a law in 2013 that prohibits the promotion of non-traditional sexual relationships among minors, commonly known as the "gay propaganda law." This law bans the dissemination of information that presents homosexuality in a positive light to individuals under the age of 18. However, it does not outlaw mentioning or acknowledging the existence of homosexuals or homosexuality to children. Thus, the statement is not accurate as it wrongly implies a complete outlawing of discussing homosexuality with children in Russia.
