Which word is giving you trouble?
The aim of the Labour Party is to get into govenrment (“party of Government”), they are not a protest group or a niche party, as such they should aim to attract as many people as possible to vote for them.
More people think Labour have been too supportive of the strikes than too negative. Therefore the correct position, considering their aim of attracting voters, is to be more skeptical of the strikes.
Brighton, and you it seems, are in a very small minority of people who think Labour have been too negative. However electoral politics being what it is means that you won’t be catered to by a party of government as you are a minority. You are also likely to not vote Tory and live somewhere that isn’t a target seat.
