There's some sub-groups I've noticed.
Example 1. Normie shitlib
Characteristics include: Passive-aggressiveness, willingness to believe any MSM narrative, probably supported Bernie Sanders because of "muh free college and healthcare", is basically a run-of-the-mill liberal that has remained the same since 2008, they can be any age group ranging from a older zoomer all the way to a boomer, least insufferable of the bunch.
Example 2. Terminally online boomer
Characteristics include: Passive-aggressiveness, narcissism, blind loyalty to the democrat party (and they'll intentionally call this blind loyalty 'patriotism'), they're extremely supportive of Ukraine in a way that rivals normiecon's obsessive support of Israel, will sometimes try to flex their service as a toilet cleaner in the army in 1982 when arguing about gun control, is willing to spend hours debating pointless subjects, will often bring up penises and prison rape during arguments, abuses the block button. Always guaranteed to have "NO DMs!!!!!" in their twitter bio.
Example 3. Aging Gen-X atheist
Characteristics include: Extremely narcissism and egotism, only personality is reminding you they're an atheist, often cries about how religion makes people stupid, stuck in the late 90s and thinks creationist evangelical nobodies in Bumfuckville, Kentucky are the single greatest threat to America, very passionate about debating homosexuality, evolution, sex ed, and abortion, often fat and ugly, like the boomer, they're willing to spend hours arguing over pointless bullshit, is very blindly loyal to the democrat party or is a self-avowed 'socialist' or 'communist'.
Example 4. Chapocel
Characteristics include: Narcissism, passive-aggressiveness, overuse of the word 'chud', extremely insensitive despite claiming to not care about your feelings, radicalized by cartoons and Bernie not getting nominated, full blown simp for the DSA and AOC, is actually a democrat in denial, 50/50 chance of being a troon, lives in Brooklyn, Boston, New Jersey, or Atlanta, unhealthily obsessed with The Simpsons and The Sopranos.
Example 5. Twitter communist
Characteristics include: Narcissism, passive-aggressiveness, extreme egotism, insecure about their status as a trust fund kiddie, unironic follower of Hasan Piker, also a democrat in denial, probably a troon, extremely materialist, half their accounts is porn and retarded essays they call memes, blocks any RW leaning accounts because they're too busy infighting with other communists, tankies or anarchists are often their biggest rivals, will eventually leave after getting outed as a sex pest for the 3000th time and return under a new name a month later.
