> Also, solder fumes aren't toxic!

If the solder has lead the fumes are toxic. If the solder has a rosin flux the fumes are toxic, and the operator needs ventilation to keep exposure below recommended levels.

It's a bad idea to be breathing in the fumes, but obviously this depends on how much you're breathing. At most risk are people who solder all day everyday.

> If the solder has lead the fumes are toxic.

I encourage you to support this statement. Lead doesn't vaporize at anywhere close to soldering temperatures, and from what I have read there is no lead component to soldering fumes and consequently no exposure through respiration.

Rosin and particularly No-Clean fluxes do pose a respiratory hazard, so fume extraction is a good idea regardless.

Lead in the fumes is still solid particulate matter, but that's sill not something you want in you. It's not likely to be a major issue, but it's not completely safe either.

holding a pencil in one hand that has a tip at 650F isn't completely safe either.
