If the EFF actually cared about freedom, they would want section 230 gutted.
No, that's what people who don't understand the internet want. One of two things happen without section 230:
1. Sites perform moderation and are held liable for all comments. The result of this will be the sites will not allow any comments (including messages boards like slashdot). Possibly some sites will have an option to review each one, but no company wants that liability.
2. Sites don't perform moderation and are not liable for comments. Without moderation, sites will become cesspools of spam and scammers while trolls run rampant. While this is typically what people with abhorrent views are in favor of, it will result in basically all message boards becoming unusable.
Option 3.
Sites perform reasonable moderation, but users are liable for what they post. This is what we have now and matches what public forum IRL are like. People have the freedom to post but with that freedom comes responsibility and consequences. One of those consequences is that they might not be allowed on that site anymore.
