Well, I think you misunderstand me.

Subjective facts as-in those with different sources or ways of measuring information. For example, people can choose the scientific studies that they draw attention to, and find an expert that agrees with them. (Also, the way in which people use the term 'fact' often relates to empirical observation and this can be miscalibrated: what was considered objective fact sometimes gets disproved or constrained.)

Alternative facts as-in alternative selections of facts. Not merely a case of adding facts, but also in not acknowledging the facts that you don't like.

Aside: @smackay's comment is very close in meaning to what I wrote (https://news.ycombinator.com/item?id=13480772). You might find it easier to understand.
