Shame this has got de railed by the queer policing here.
I also used that word to describe me, and see it everywhere in the community from going to a pub quiz called the queer quiz, to queerkulele (a ukulele band) and everything in between!
As shock horror a non lesbian in a relationship with a lesbian, I've spent fair amounts of time in uganda.
Previous posters have it right that male homophobia is much more prevalent than women. We are only 6 years past the death penalty being agreed for male couples, although that's now been repealed but there was a surprising amount of support for it. There were also fairly public outings in newspapers, lots of the legal prosecutions are aimed towards locals and men.
It's not simply a country where gay marriage isn't legally protected as others have said, its a country that has repeatedly raided gay bars, and has repeatedly tried to push through death penalties, or long criminal sentences for acts of homosexuality (usually men)
That being said....
I had zero problems as a queer woman at that time. Its not a country I would take my wife, or really return to now I'm married. There was distinct lack of curiosity about female sexuality, so you'd often find people who we would assume are gay, or lesbian if we saw them in the uk being assumed as straight in uganda.
I didn't disclose my sexuality at all, and made sure I completely deleted everything. I've no doubt that if they had found my Facebook and realised there was evidence of my partner that my working relationships would have soured and it would have spread quickly. Some people in the community are clearly allies but I had to bite my tongue alot as its fairly common for people to openly share their beliefs about homosexuality and hell.
As is normal in most countries, people did seek to add me on Facebook etc (even in rural areas)
It's been interesting since I've been back home, subsequently married my wife to see how that impacted the friends I made. Some will happily comment on Facebook photos, others sent pleas for salvation and others completely disappeared
I worked in a health care setting and it was difficult for me to hear the judgement placed on patients who were identified as queer.
Ultimately I would be more concerned now that when I went I would be legally recorded as being in a same sex relationship which is more discoverable. However it was fairly easy to be incognito.
For me it would depend on the length of the assignment. There's only so long I'd be willing to pretend to be single, not display any pictures of my wife, and hide my online presence for.
On a side note, if you say you are married and are there for a long time, then its natural that people would ask for details of your husband and photos.
