you don't have to move over for bikers, and if you feel that they are riding irresponsibly or selfishly then don't but don't deliberately block them either

i agree that some are a nuisance and that training and education are needed - and not just for the bikers but for all road users

but what is the harm in a bike using the bus lane to get to the front of the queue rather than a more dangerous area of the road? you could argue that why should they get to the front anyway, but they do and that's life - accept it and don't get in a jealous rage about it. it's just one of the benefits of being on a bike in traffic. car drivers can have different benefits like listening to music, having heating/aircon, keeping dry, smoking etc.

in life, sometimes you're the pigeon, and sometimes you're the statue. car drivers in traffic queues are the statues getting shat on by the biker pigeons
