No, you shouldn’t reflexively take the opposite version. However, when the entire pantheon of leftism is on your side, you should take pause. On your side there is Trudeau, macaron, Merkel, Biden, Hillary, Obama, Schumer, Nadler, Boris Johnson, the vindman brothers, Victoria Nuland, the woke DOD, the entire MSM, all of academia, CNN, New York Times, Mark Zuckerberg, Sean Penn, Abramovich the spirit cooking woman, Schwab, the WEF, all of Hollywood. Etc. The list is endless. Every single woke, pussy hat wearing, BLM supporting person on earth is all in for Ukraine.
If one leftist says something that you happen to agree with, no, you shouldn’t reflexively take the opposite position. However, when the entire Greek chorus of leftism is 100% in lockstep with you, it’s probably you in the wrong.
“However, when the entire pantheon of leftism is on your side, you should take pause.”
Nah, that’s the opposite of critical thinking. If you have reasoned properly, it doesn’t matter at all who agrees with your who disagrees with you, or how popular or unpopular your opinion is. If everyone on the left says “the sky is blue”, I am not going to question my own assessment of the sky’s color one bit.
