Well I use cuss words, don't know about "abusive" words. Thoigh cuss words can be abusive and offensive but in this ngày and age they're thêm a part of mainstream culture and language, so they can be used in a fashion that is not abusive hoặc offensive. I generally use them in what I intend to be a NON-offensive/abusive/derogatory manner. Though if someone plucks my nerves enough I won't hesitate to be extremely foul mouthed. Honestly it's not that it it makes us sound cool cause that never even crossed my mind it's just what I use on a day-to-day basis cause these days its mainstream culture.
People have the right to say what they want on their profiles. It's as simple as that. Do we always have to like it? No. There are some cases in which people are malicious to others through their profiles, but bad language isn't something to be prohibited on personal profiles simply because people have the right to say what they want on their own page.
The only case in which this doesn't apply is when others' rights are being demeaned through someone else's actions.
I think it does the opposite, it makes the people who use inappropriate language look very stupid, immature and unaware how to speak normally for an average conversation. But people do have their reasons sometimes so give them a chance, plus it is their own profile, let them do what they like as long as it doesn't involve you.
I can be a bit of a yandere (see Yuno Gasai/ Kotonoha Katsura) so I might swear/ be violent, but I can't help it.
Oh yeah, funny thing is on your thông tin các nhân you've got the same pictures that some old fanpopper Ati had, ain't that just the coincidence ha....ha.... -_-
