Kek sorry I got distracted by the op pic. Guess I'll try and answer the question.
>How does social media affects and causes our change in behavior?
Different social media forces us to behave differently based on the 'culture' inherent to that particular social media. This 'culture' is then maintained by the user base of that website, usually through peer pressure. I think this is pretty obvious but for example, I can't go on twitter and toss the words 'faggot' and 'retard' around without being ostracized and kicked off of the platform. Similarly, it would be stupid of me to whine about the usage of those words on an anonymous imageboard and expect to not get bullied for it. This is just how things are; you either conform and 'integrate' or you get othered. Real life works this way too now that I think about it.
Another thing I've noticed is how social media has desensitized us to the amount of information we share online. They used to tell us to never share any personal info online but now if I want to sign up for any social media I need to input my phone number, date of birth, shoe size, whatever the fuck. It boggles my mind that no one on these platforms seems to be even slightly concerned by the amount of info they need to share just to be able to use the platform. Hell, most of them seem eager to overshare as much as possible about their mental illnesses or shitty family situations or whatever. How are they not ashamed of broadcasting all that to the whole world on an account that has their real name and face attached to it?
The effects of social media on offline behaviour is a bit different. I've noticed people who act like they're hot shit online rarely have the guts to act that way in real life. It's like the anonymity of hiding behind a screen gives them the courage to act like shitheads (getting kinda meta here, considering what site I'm on kek). Of course there are retards who can't help but bring their online faggotry into real life and that's just fucking lame if you ask me. The other day, my younger sister was telling me that I can't use the words 'psycho' and 'schizo' as insults because that would be ableist. Naturally I told her to fuck off and grow up because real life isn't twitter and no one fucking cares. Pic very much related kek
Okay that was all over the place but that's my two cents.
