Talk to them on their level. Don't talk down to them or come across like you already know better than them. As an idea, you might try playing ignorant to them about a piece of information or news event (do your homework and plan ahead), and approach it with their perspective (i.e. start by innocently obliging their opinion about it) but gently lead it into a corner (which should be easy if they lean to the left). Then introduce the better perspective (or lead them to discover it) and let them think about it (i.e. don't force it).  It would be a good idea to get a good assessment of their overall view of things before you form your plan on how to engage them with your own ideas. Ask them a few preliminary questions to get their views without immediately pursuing further. Make notes if it helps you.  Main topics of consideration and a few thoughts on them to get you started: Racism - There are no real racial differences, only cultural (education, relgion, economics, etc.). Free speech - Words can't hurt anyone. Sharing ideas/opinions allow for educational growth. Gun control - It's much safer for the public when a lot of law-abiding people have/carry guns than when they don't. Transgenderism - Sexual disorientation of children confuses the natural pressures of their pubescent sexuality. Leading prepubescents to question their sexuality is brainwashing. Globalism - Globalism is founded on the centralization of power, which is leading to monopolization of people, resources, products, etc. Diversification is the opposite of globalization. Open borders destroys nationality, which holds people and their cultures together as a unit with similar values, goals, beliefs, etc.
