There shouldn't be any need to build consensus – the behaviour described by the OP is plainly against Wikipedia policy.[1] That's not to say that it didn't happen, but it's important to be clear about what caused the editor's bad experience. Sometimes it's rogue editors and sometimes it's overly pedantic enforcement of policy, but edits are often reverted for good reasons.
