"The reason some people don't listen to you is because they don't respect you. Don't get angry, just move on. Don't let those who don't respect you stop you from talking."
There are always going to be people out there that show you disrespect and who try to get you to stop talking. You can't let those people stand in your way. This goes for things that you do, or want to do, as well. Just because someone wants to be disrespectful toward you because of things you say or do, that shouldn't stop you. It is not you who has the problem, it is them. Keep going, keep talking.
