First, you must know that we are NOT against animal rights in general, but we are against the methods PETA uses to acquire them.
PETA is bullshit for the following reasons:
1. They fund terrorist organisations to firebomb research centers
2. They are hypocritical, killing 97% of animals they take in.
3. They use most of the money they receive in donations to advertise, instead of spending it on helping animals.
There are much better organisations that PETA who will put donations to a much better cause, but donating to PETA is funding terrorism.
We can weaken PETA by trying to convince its members to stop donating and supporting PETA, and instead find a charity that is not bullshit.
Only show the evidence, don't argue, leave them to make up their own decision once they know all the information that we know about PETA.
