Regardless of your beliefs or persuasion, or perhaps because of them, it is important to acknowledge the bullying crisis in our country among teens & young adults. If you do not agree with a certain lifestyle for any reason, particularly as a result of your personal faith, it is critical not to be hateful, degrading, or unkind to others. There is NOTHING in Biblical scripture that would encourage any person to bully another. In fact, scripture is quite clear that the contrary is true. We MUST love one another. We must uplift one another.
The last one is my favorite. 1 Peter 4:8 Above all, love each other deeply, because love covers over a multitude of sins.
