I've never knowingly encountered a transwoman. But recently, in India, I saw a few hijras.
I've been going to the same South Indian town almost every year of the last 45 years, and I'm pretty certain there are no local hijras. But while I was there a huge Hindu festival took place at full moon, with about a million people from all over India descending on the town for a day or two. These pilgrims are well-behaved, peaceful people. There are normally never any incidents, violence, etc. They come, do their thing (praying, pujas, singing etc) , and go again. The worst that happens is a lot of rubbish left behind for the town to clean up.
The first encounter was when I was walking down a quiet lane with my daughter, who was carrying her toddler. The two hijras coming towards us wore saris and full make-up and, as almost all Indians were doing, looked at my granddaughter, laughed, and made kissing gestures. (This is quite normal; Indians, men and women, delight in small children and make their delight known, even to strangers, pinching baby cheeks etc.)
So far so good. I was just bemused, not having ever seen a hijra before, not even in the cities, and here, of all places!
Later on, my daughter and her husband reported that they'd seen a couple more hijras, being quite aggressive in the crowd, threatening and bullying people and creating a scene.
Later, I was myself in the crowd with my son in law and saw with my own eyes, a very tall, burly hijra, standing in front of a short Indian man, harassing him, shouting, pushing in the chest, etc. Son in law conjectured that they came expressly to pressure weaker men into giving them money.
There were a couple more sightings, each time demonstrating obvious bullying.
This is a new phenomenon; that they* come to a normally peaceful celebration and scare people out of their wits. In each of the bullying scenarios, the men they were intimidating were puny, weak looking fellows.
*OK, nahalt. Not all hijras are like that.
