The best way to counter this is talk to people one-on-one well before the AGM and explain the purpose of your motions and how they would work. Encourage your neighbours to come to the meeting but be aware that some people are very conflict averse and may not show up if they think there will be anything approaching vigorous debate. Encourage these timid people to appoint you or an ally as their proxy.
I have learned that people often won’t read more than a paragraph or so but will listen to someone talking. Also people often don’t read meeting papers until the day of the meeting. So, you might counter the committee’s written position more effectively than you expect.
Make sure your proposals are consistent with the legislation. Nothing would shoot them down faster than being beyond the powers of a general meeting to decide.
