Okay kiddo, so Christianity is a religion that believes in a god named Jesus Christ. One thing that has caused some debate in Christianity is the topic of sexual orientation. This means who someone is attracted to romantically and sexually.
Some people believe that Christianity teaches that only heterosexual relationships are allowed, meaning people who are attracted to the opposite gender. They think that any other type of relationship goes against what God wants.
Other people believe that Christianity teaches that love is love, and that people should be allowed to love whoever they want, regardless of gender. They think that being attracted to someone of the same gender is natural and normal, and that God loves everyone equally.
There are different interpretations of the Bible, which is the holy book of Christianity, on this topic. Some people use certain passages to argue against homosexuality, while others interpret those same passages differently.
The most important thing to remember is that we should love and accept people no matter who they love or how they identify. It's important to treat everyone with kindness and respect, just like Jesus would want us to.
