"You're against what?"
To be fair it might lead the curious to asking more about what they are about.
"You're against what?"
"Well, you know how some people are activists against cancer, and raise money for cancer research and treatment? And some people are activists against Parkinson's disease or Alzheimer's, or HIV/AIDS, or other things that kill people? And other people are against drunk driving or shaking babies or unsafe working conditions or other causes of death? Well, we don't discriminate — we're against all causes of death."

This was first legally approved political action of Russian transhumanists. Symbolically it was near Karl Marx monument which is opposite to the Big theater.
Main slogans:
"Stop aging - it is main goal for the state".
"Live 150 years!"
"Immortality!"
"Right to live!"
"We are against death"
The main cognitive bias that played here was that we will be crashed by police. Nothing happened.
