Nobody posted any slogans until you did. It’s perfectly reasonable to reply with civilized discourse.

Unilaterally proposing a single solution to a complex societal issue while insulting dog owners is problematic and does more harm than good. “Adopt and shop responsibly” doesn’t offend anyone who bought a dog and might make someone ask, “What does it mean to shop responsibly?” instead of buying a dog on Craigslist. Dogs deserve more respect from people, which requires treating all people with more respect.
