People are so concerned about tracking cookies, privacy invasions, spam, etc, and then they go and volunteer their names to the government headed by a committed marxist!
Personally I think the petition website is a propaganda tool for the president.
He finds Liberal issues to use in his propaganda and has the added benefit of collecting email addresses for his campaign machine.
Any conservative issues can be easily ignored with zero consequences. He wasn’t going to get their votes anyway. And yes those addresses can be filed away just incase they’re needed.
