If you poll non-shomer-shabbos Israelis (that do have some religious background, as opposed to 100% תינוקות שנשבו who know a nothing, or close to nothing about יידישקייט) if they are reform, conservative, or just non-observant, I would guess that an overwhelming majority would answer non-observant (לא-דתי).
However, in America I have heard of people being very religiously conservative, or reform.
Do you see the difference? The former say, I don't adhere to religious laws. The latter say, I am changing the religious laws to suit me. I define the religion!
Idk how much you guys "get out there" in the secular world but here's a story for you, I had a coworker a few years ago I became friends with who ate dairy out and his family didn't keep shabbas at all growing up. While in NYU he met a Rabbi that he's still in touch with this to this day, drives out weekly at night to learn with him. As we chatted more and more, he made strides in eating out less, fasted with me whenever I told him it was a fast day, and just in general had many good conversations about Jewish philosophy. God plays a big part in his life, he's doing his best, and it made me realize how much I took my "head start" for granted. Some of you would call him conservative, to me he's way frummer and more genuine than myself, who you would probably call "modern orthodox" if you saw my spec sheet (I keep shabbas, kosher, but I'm not perfect and don't daven with a minyan except on shabbas, I don't learn enough and I grew up in JDS system with 0 excuse).
