It's not lazy it's obvious and necessitous. The right is about the individual, about personal gain, the left is about working together for growth as a society. So the right has no need to group together for strength as a group, the left does.
Of course the right does create lazy groupings for negativity, scroungers, immigrants, single mothers, black criminal gangs, (muslim) terrorists etc.
The BAME grouping, is collecting together people that are racially oppressed, to work together. It isn't saying they are lessor, just that they are treated lessor. Same for LGBQT
