Probably with running a bunch of independents at the local level. You can’t do what the Greens tried and drag out an asset for the top position every four years with nothing else to show. Start small and get people used to the idea that it’s okay for someone outside of the main parties to hold office. Build results then form a party from the independents once you’ve had some successful incumbents.
I’ve never had problems using terms like “look man,” “oh boy,” or “dude” In “normal” conversion with anyone until recently. I was talking to a trans-woman I know and definitely stopped myself from dropping “hey man” in our conversation because I thought she would not appreciate it. That’s caused some self reflection and while I’ll probably continue to use genderbent language when talking with my wife I’ll probably seek to minimize it elsewhere. I don’t really know how in tune a given woman I’m talking to is with their muliebrity and it seems not my place as a cis man to make that determination for them.
I would say for a lot of people it probably doesn’t matter, but for those that it does it does a lot and it’s no skin off my back to try to be courteous in my speech with whomever.
