Banning gender affirming care is a direct threat to trans people. Gender affirming care is a collection of lifesaving medical treatments and banning it denies trans people the fundamental right to exist. Refusing to spread a life-threatening disinformation campaign in Canada or hypothetically in the US is a strategic decision to defend life and liberty.
We do not need to tolerate intolerance. Nor should we. Tolerance is a social contract or peace treaty. When one group, such as fascists, break that contract, they are no longer protected by that social contract.

Amendment I
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
A person’s freedoms do not end when they break laws, rather there are no laws against our freedoms. A person’s freedom to swing their arm ends at another person’s nose. The freedom of speech ends where a person’s right to exist begins. Allowing fascists to trick people into banning lifesaving medical treatments isn’t speech we should protect. As it infringes on the right of those people to exist who depend on those lifesaving medical treatments.
In the US, we are a nation of freedoms. We write laws to protect those freedoms. When the laws infringe upon our freedoms we change the laws.
