Mod-80, some of those things in your list are worthy, and others are not. It is difficult to know what exactly is the right thing for a Jew at any given moment.
For example, I doubt any Chareidi yeshivos in Israel have any organized sports, or even a gym to play in. Yet, it is pretty well-accepted that getting exercise is necessary for good health. All modern orthodox schools encourage sports in one way or another.
I am willing to bet that most Chareidim in the USA follow sports to some extent, and all have heard of Babe Ruth, etc. To a Chareidi in EY, the Chareidim in the USA are modern orthodox.
So there is really no definition of modern. It is how much we take from the outside world in conducting our lives. We many not dress in black and white, but we often have tzitzis out, and all of us, except in rare circumstances, wear yarmulkas. SO we don’t hide our Judaism, but we try to dress in whatever way is considered dignified in the current times. That is how we interpret lo shinu es malbusham, dignified, and with tznius, not necessarily black and white.
We speak a pure English, not mixed in with all kinds of Yeshivishe and Yiddish words. But we speak with refinement. That is Lo shinu es leshonam, the manner of speech, not the language itself. With kindness, patience and staying away from nivul peh, etc. We do not believe one needs to speak Yiddish to be frum.
As far as movies or novels, one would hope that one reads kosher books, or sees kosher and educational films, not containing inappropriate scenes. Yet, we don’t say all movies and books and TV are asur. It is a case by case basis. I let my kids watch a little sports, and I like to watch election debates and returns. Once in while there may be an educational show worth watching. I personally believe that most TV is a waste of time, yet I don’t subscribe to the view that TV is a toevah and forbidden. it all depends on the use. Same with a phone. One can call bad places or good places. And of course the internet is a far bigger problem than phones and TV. Yet we use internet, and try to maintain self-control not to go to bad sites. I believe most Chareidim in the USA also use internet. So this further proves that USA Chareidim are really modern orthodox. They also go to concerts, etc.
Many Chareidim in the USA also go to college in some form or another. The entire Agudah membership is baalei batim many of whom are professionals, i.e., doctors, lawyers, accountants. All of these require degrees. So USA chareidim like to denounce the MO, when they themselves are far more like the MO than like the Israeli Chareidim.
So it is all a matter of where one draws his own personal line. There really is no line. As far as denim, many Chareidim in the USA also wear denim, especially on Sundays, or if they are in professions requiring manual labor. I see them wearing a hat and jacket over the denim and T-shirts all the time.
BTW, do you really believe that American Chareidim are less likely to have visited an inappropriate web site than MO are? A person’s yiras shamayim is a private and personal struggle and has nothing to do with labels.
