There is a big difference between promotion and description An encyclopedia should describe a subject objectively and neutrally If it promotes an idea it becomes an advertising tool which Wikipedia shouldn t be Describing consists of recounting facts Promoting involves making subjective judgements about the facts and encouraging behavior To include facts is not promotion although doing so while leaving out other contradictory facts is biased and can be considered promotional So the correct way to deal with pseudoscience or any other article for that matter is to describe the relevant verifiable facts about the subject whether positive or negative As for Lerner being notable he could be considered notable on two separate subjects his cosmology work and his fusion work His cosmology work received more attention in the 90s but he is still active in it today and has received some media attention His fusion work is more recent and has received some media attention as listed in the references
