I don't see this question about Omission of if in a conditional phrase as being the duplicate of Must conditional sentences begin with “if?”. Yet this is the stated reason for the closure of the question. The answer of the supposed duplicate is scarce and does not deal with subjunctive really. Also, the closed question has a second query that has just been glossed over as non-existent. Is that on?
Are we not too quick to close? Just wondering...
