As mentioned before, you can't stop individuals using a system and finding ways to make it advantageous for them. But you shouldn't then make it impossible for everyone else to use that system to live a normal life.
I will use refugees for example, lets say one foreign national comes over and takes refuge, the reason not important. They then commit a heinous act should every other person claiming refuge be punished? No you know that too as does everyone else here.
But that was the mentality we saw only in May when a lie sparked national riots, when individuals tried to take over my town set fire to Mosques, damage shops, loot and threaten anyone that looks foreign to them (Including breaking into Refugee hotels). All for what a perceived risk or someone gaming the system.
There are literal campaigns for women to consider all men a potential threat, but a small subset of those men being given the cover to enter female safe spaces without question is fine?
I understand it's horrible that these things happen, and that genuine, non threatening trans people may come under suspicion, but it's called safeguarding.
If my nephews needed picking up from nursery, i couldn't just go and pick them up, unless i was registered. Same goes for my girlfriend, who is their actual blood relative. It might be seen as an inconvenience in most cases, but its put in place to stop the small percentage of times it might actually be a risk.
I'm sure some people simply refuse to see the dangers in order to make it sound like a bigoted take.
Chances are, the people going into safe spaces to commit these types of crimes, are not actually going to be Trans, but they use the laws to protect them anyway.
Someone in here used an example of being a teacher, and being forced to acknowledge a brat kid using a different gender identity specifically to get a rise out the teacher, or even getting them in trouble if they refuse to play along, and its a valid point.
It's noble standing up for everyone to have these rights, and that is fine. But on the flipside, there are also the existing rights of others that are being compromised.
Like i say, it's not anti Trans, it's common sense.
