Maybe I’m being a bit paranoid but we should always think safety. I think you should wear the badges at work where there is a controlled environment but I would hesitate wearing them on public transport because you never know who you will run into. As we know, some people take offense at LGBTQ people and in a public situation it may get out of hand. I would really hate to read of someone confronting you in a bad way. But thats just my opinion, I’m sure others will vary.
