Is harassment the price of beauty?

Dear George
I live in a small market town, in a busy street. As you can see from the photo, I enjoy sitting on the end of the fence, when the weather is suitable. However, I am harassed by humans.
Some of them just stop to admire me. Some take photographs (like this one) which I feel I have a duty to the public to tolerate. Naturally these are spread about social media - but that is the price of beauty.
However, what I loathe is humans that want to pet me. They seem to think that I will enjoy this. Why? I am a cat who is careful about her friends. I only admit a few humans into that category.
So why should any old passerby think I want their sticky hands on my fur. They have no right to intrude into my personal space.
How can I prevent this?

Dear Snowflake,
You need to be more proactive when you see humans approaching. Put your ears back as soon as you see them. Crouch lower and bare your teeth. As soon as they are close enough, hiss loudly. Any closer, give them a good scratch!
Be honest.... Are you enjoying the admiration too much? Do you like being a Facebook pin-up? Your serene and beautiful demeanour may be causing the problems in the first place. Think about changing your image from beauty to the beast.....
Yours 
George
