The strong feelings around the term Engineer partly date from the historical context, where inadequate engineering was more commonly and directly reflected in real human deaths. This was a huge motivator for the title of engineer to become codified and locked down to a specific set of proven and repeatable skills.

These days, most long-established engineering disciplines and similar professions are codified to the extent of having member's-only institutions and charters, and basically become "old boys clubs", including ranks and rituals.

Hence there is a divide, between these old schools of engineering and their exclusive ways, and those who use the term engineer more broadly and literally.

The old boys club mentality has many flaws, but they do have that one strong original point: that the harm one can inadvertently cause to others, under the title of engineer (or any expert), is proportional to the expertise claimed. If you claim you can design bridges, then it's incredibly important that you're right - else deaths.
