Self-righteous in all the wrong places.
Long story short, Tatsuya seems to be a guy that was doing his dudebro thing, then either got educated on social justice or decided to start incorporating it into his comics.
From a pure enjoyment perspective, I honestly can't vouch for much of his later stuff. About 90% reads like an illustrated blurb by a social justice blogger. For the most part, this is morally good, but makes for repetitive and emotionally draining reads. What I remember of his earlier strips seemed pretty good: usually funny and with a progressive attitude. I'm not sure what changed though. An archive binge of his new stuff will make you actually laugh maybe once or twice, but engender many groans through how anviliciously he tosses around otherwise sensible morals.
Tatsuya is certainly a complete tryhard when it comes to gender politics. He reads like the mirror universe counterpart to a conservative cartoonist, complete with a weeping Lady Liberty. Yet, however much Tatsuya views himself as a white knight, his strips still often uphold many harmful views to women. Most common of these offences is a prominence of slut-shaming, with sex workers portrayed as fallen and corrupted victims of the patriarchy, rather than... women who are sex workers. Slut-shaming attitudes usually seem to be an overflow of his VERY accurate and appreciated criticisms of the porn industry, though, which at least explains, but does not excuse, his actions.
Anyway, word limit looms in the distance, which prevents me from going in-depth on all these talking points, so I'll just rattle off what I can remember to put down. Also, I haven't read every single strip, so if there's any you'd like to bring up as counterargument, please do. Alright, here we go.
No trans or genderqueer characters to date, trans rights never brought up. Tatsuya possible rare male TERF? Must investigate further. Pretty much everything DMH said. The part about Sarah Palin is irritating for obvious reasons.
Satan has gone from a comedic representation of generic evil into just a sexist dude, which is boring to watch.
Satan is a brony, and as a person who hates bronies, I like this.
Not totally sure what most people more into the hardcore feminist movement would think, but his use of "Kill All Men", etc. seems... appropriative?
That's all that'll fit. I encourage comments!
