Different writing groups and critiquing circles will have different memberships, but it’s not that unusual to find a percentage of both teachers (of varying sorts) and editors (also of varying sorts). This is a great resource in any group, as these are people who spend a lot of time with words, structure, grammar and doing proof reading.
They are also used to providing criticism with a very authoritative manner, and this occasionally leads to a limitation in a critiquing situation. With every good intention in the world, they can provide feedback in a way that says ‘you must change this’.
As long as you, as the author, have the confidence to treat this as an opinion, not a fact, then there’s no issue. But a ‘loud voice’ can be hard to resist simply because it seems so confident!
Obviously, this is why you have discussions about how you give feedback, when a group is set up and again when each new member joins.
