"Nunca consideré una diferencia de opinión en política, en religión, en filosofía, como motivo para alejarme de un amigo."

Simplified Meaning:

It's saying that people can still be friends even if they don't agree on things like politics, religion, or beliefs about life. Think about it like this: Imagine you have a friend who loves a different sports team than you do. You might cheer for different teams, but you still enjoy spending time together and having fun. In the same way, you might have different opinions about larger topics like who should run the country, what religion to follow, or how to live your life. But those differences shouldn't make you stop being friends. Good friends accept each other for who they are, even with different ideas. So, if you disagree with a friend about something important, remember that it's okay. Focus on what you like about them and the good times you share. Being able to have different opinions and still be friends makes the relationship stronger and more interesting.
