OP- there are clubs and activities which are going to attract a more serious student than open parties.
Who is attending the poetry readings? Who is showing up when a professor moderates a political debate between two local candidates? Who is the “business manager” of the choral society, madrigals singers, Morris Dancing performance group? Who runs the coat drive for the homeless in your town? Who is working with the local school board to pushback against the people trying to ban “Maus” or “Diary of Ann Frank” as being too lurid for HS students? Who is working with the food service union and the management of the dining halls to create a food scrap composting program, reduce single use plastics??
These might be your people. You may need to go outside your comfort zone (what the heck is Morris Dancing?) but trust me- the students who participate in these things are likely not at college to party, and have broad interests which may coincide with yours.
Does the town you live in have a muckraking, alternative news website? Many do. And if not- why not meet with a few of your professors to start one? These are the news sources that report on important events and problems which don’t get adequate space in the traditional press.
