Yes, it is very important for Christian teens and Christian college students to protest against musicians and actors who support gay marriage, because gay marriage is fundamentally opposed to Jesus Christ and the Holy Bible.
Christian teens and college students should take to social media to attack singers and actors who support gay marriage or gay rights, because homosexuality angers God.
Christian teens are NOT too young to fight for Jesus Christ and let the singers and actors know that Jesus Christ is important. That is what loving Jesus Christ is. Fighting homosexuality is loving Jesus Christ!
God exists, and God hates gay people, as is clear in Sodomand Gomorrah, where God decided to kill all gay people, refusing to send any missionaries.
