Nobody is holding their camera on some salaryman about to enter a soapland, commentating how they're about to fuck. Well, at least not any people with a brain. All the people "walking by" give just as many fucks about a guy with a camera as they do about a guy standing around with his phone in his hand chatting on LINE. It's 2022 and for better or worse, cameras, smartphones, streams and all the other shit is part of society now so I highly doubt that the average Japanese person is offended when they appear on some guy's video for half a second, masked up at that. On the contrary, more often than not people actually want to engage with someone because of the camera and find it interesting.
Yeah, I agree - if someone points a camera at a random person and just films them for multiple minutes, that's stupid as fuck and disrespectful. Anything else is an overreaction and out of touch with the times. It's not 1990 anymore and this applies to a bunch of things I've seen people say on here.
