For the benefit of @Lurker I will post the dictionary meaning.

Do you really think you will change people's behaviors with DDF posts (or any other way within your means)?
Or as they say in Israel: בכביש אל תהיה צודק, תהיה חכם!
I post on here because I owe DDF a great debt. I did not take Covid seriously until a little before Purim. The information posted here was invaluable in educating me in what was (and is) going on, and how to keep my family safe without locking myself in a room and losing my mind. In turn, that information was shared with my family, friends, and community, and from there it was passed on to their contacts, and on and on. Does everyone take me seriously? Hell no! I get laughed at more often than not. But to some people, the posts of DDFers like
@yuneeq @S209 @Yard sale @aygart @Dan @CountValentine @Afrages6 @biobook and many, many more have had a huge impact on the lives of countless people they will never meet. It's ironic that it's you who thinks they don't make a difference. I can't count how many Twitter threads and articles YOU posted that were influential in guiding the decisions that I have personally made. I can't speak for others, but I doubt I'm the only one.
I used to be a cynic. I lived my life wanting to die. What is life when nothing matters? Then I grew up. Cynicism isn't what happens to frustration when you get older; it's what happens when you stop trying to address your frustrations.
There have been a number of comments recently about the changes Covid has brought about to people's personalities. Your posts make me question how Covid has affected you. You are DDF's ultimate Lubavitcher. Your profile picture is 770. The most painful part of the restrictions for you was your inability to daven in 770. The way you talk about your family, your interactions with others, farbrengens, hashkafos, life; everything about you screams I AM A CHOSSID OF THE LUBAVITCHER REBBE!! How can you sit here and tell me that one person can't change anything in the world? That nothing I say on here or do in my life offline can change people's behaviors? Who are you?! You're going to blame old age for cynicism? Throw in the towel, become a fatalist? This is really what you think of life now? This is a Lubavitcher??? And they wonder why people are shocked at the transformations they're seeing in attitudes and behaviors of their peers and acquaintances, family and friends, people they love and respect.
