This is a YMMV thing. It depends a lot where you live. Obviously, you know your community better than I do.
I live in a small village of maybe 300 people, including the surrounding farms. I had community connections in a nearby university town, population about 4,000, and in the city, population about 400,000.
I came out to the community association in the village in person, by standing up at the weekly coffee group and making the announcement. I had some odd looks, but everyone has been either supportive or accepting.
I came out to the local (village) fire department, where I am a volunteer, by phone to the chief (so he wouldn't be surprised by gossip after I came out to the community association), then by standing up at the monthly meeting and making the announcement. Again, no problem.
I am a member of a concert band in the nearby town. I came out to them by email to the group mailing list, basically saying that by the next practise, I would be Kathy. I had lots of support, both by email to my announcement, and in person at the next practise.
I am also a member of an astronomy society in the city. Like the band, I came out to them by email to the group list. And, like the band, I had a lot (and I mean a lot!) of support. I did a Powerpoint presentation to them on telescope selection a few months later, and it was a great confidence-builder.
Since coming out, I have gotten involved with a community theatre group in another small town, population 6,000. The people there have only ever known me as Kathy. Theatre people tend to be very LGBT-friendly, and I have had no problems there at all. I am now in demand as a sound-and-light tech.
So, although my wife and I had made a rough bail-out plan in case my coming-out went badly in the village, we didn't have to use it. That plan would have involved moving to the university town, where we didn't know a lot of people, but knew we would be accepted.
I know I am lucky to live where I do. It doesn't go that well in most places. And, this being Thanksgiving Day in Canada, let it be known that I am truly thankful for where I live, and whom I live with.
Like I said, YMMV. You have to make your best guess based on people's attitudes where you live.
