The KIDS act (which contains KOSA) passed the US house, so I recommend calling your senators and telling them to vote in opposition. I don't think I need to stress the importance of being able to use the internet freely and without privacy barriers being breached.
There are many scripts online you can follow, many ways to tweak your message to fit your senator (ESPECIALLY if they are up for reelection this year). Whether it's a recording you reach or a real person, be straightforward, don't argue, just let your rep know that you are a constituent and you oppose the KIDS act, etc.
Here is where you can search for your senator... call, email, fax, bring them physical letters, show up in person to their offices if you are able.
