The ambiguous wording doesn't erase the fact that this is your rejection of the assertion you later accepted.
Huh? There is no ambiguity.
I am saying (emphasis mine): ""I don't see any retreat from the collectivization in the mid-30s". Note: "in". What you are implying I said is that I don't see any retreat from the collectivization after the mid-30s. These are different sentences with different meaning.
as being in competition
It's not a competition, but if you want to claim some authority ("I do have some idea what I'm talking about"), it would help to not bounce between claims that are wrong ("The mid 1930's had the first semi-capitalistic change") and claims that are not even wrong ("the USSR would briefly swap over to a semi-capitalist system for a few years").
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
