It seems that some just skim over the posts and then post something based on the main words that caught their eye without really reading.
Some refer to being lax as “modern”. While others automatically add the word “orthodox” resulting in people being labelled unintentionally as “MO”. Not everybody who calls themself “modern” or uses the word “modern” as an excuse to violate halacha consider themself “MO” or part of the MO community.
