That's great. That means that current politics aren't focused on making your life worse, or making you feel unwelcome. That means things are pretty good for you.

This is not the case for every one else. For many people, "Make America great again" is the slogan of people who hate you, who don't think you belong in your home, or who might even want you literally dead.

For them, it's not great hearing that phrase used as a joke.

The fact that this does not apply to you, personally, is not a reason to dismiss them.
