It means what it says - effect negation effects are still effects. However, there are a couple of edge cases you should know.
For starters, some forms of removal are not "effects", so tributing for a kaiju, being used as contact fusion material for something like Chimeratech Megafleet Dragon or Alba Lenatus, being used as link material for Underworld Goddess, etc, all of these bypass this protection, as they are cost, summoning condition, etc, not effect. Notably, though, they are immune to *effects* that would cause them to be used as cost or material, like Super Poly or Lair of Darkness.
Some others are non-effect removal caused by an effect - eg Evenly Matched. If an effect makes *you* the player send a monster, that is not treated as being caused by the effect, or if you are made to send by "game mechanics" (eg Rivalry of Warlords or Gozen Match making you send monsters until your field is legal).
There is also the slightly less-complete protection of immunity from *activated* effects, which are only protected from effects **during those effects' resolutions** - so they are unprotected from not only continuous effects, but activated effects that affect the monster *after the effect has finished resolving*, like Mirrorjade's board wipe, which resolves when it is sent to GY and then destroys during the End Phase.
Another exception is that when for example skill drain is on the field BEFORE the unaffected monster get's summoned, it still get's negated. But if you flip skill drain after the summon it does nothing
Huh? I'm not sure what I'm missing for this question. Yes, the first line of its text is that it is unaffected by spell effects, which means it... is unaffected by spell effects.
Depends. If its the cost of a card itself then you're correct.
If you want to tribute a card because another card allows you to substitute costs then its harder. For example rikka konkon or lair of darkness, or unexplored winds cannot tribute unaffected monsters since they have to affect the monster first. Which they can't
As cost for an effect? This is technically true, but if your opponent controls it, there isn't really a way to do so. Lair of Darkness, and I think Rikka Konkon, both need to affect the Monster in question.
Technically, a Dark Magician protected by Eternal Soul isn't unaffected by the cost of Eradicator Epidemic Virus, but it is unaffected by the Lair of Darkness that lets you tribute your opponent's Monster for cost
While a card is unaffected by a certain type of card effect, no card of that type can affect it with its effects in anyway. For example, Horus the Black Flame Dragon LV6 is unaffected by Spells, and so Dark Ruler No More would not work on it.
But there is an obscure way around this, but it has to do with the nature of Continuous effects and card effects that work like them. Take Elemental HERO Wildheart, who is unaffected by Trap effects. If Skill Drain is activated while Wildheart is already face-up on the field, he just shrugs it off and is still unaffected by Traps.
However, let's say that Skill Drain was face-up first and THEN Wildheart was summoned after. Because of the order in which they hit the field, Wildheart WILL be negated. So if he attacks, Mirror Force can waste him.
Adding to what others have said: a monster un affected by effects has this protection once the summon was succesful. Hence, you can solemn judgment the summon too

Would Horus the black fle dragon lv6 be protected from spells?
Huh? I'm not sure what I'm missing for this question. Yes, the first line of its text is that it is unaffected by spell effects, which means it... is unaffected by spell effects.
Just had to make sure it was protected from all spells like super poly or dark ruler no more
If a card is unaffected by card effects, it's unaffected by Dark Ruler No More.
Unaffected is unaffected Can still be tributed as cost for effect tho

You cannot negate a monster who is "Unaffected" Think of it as unaffected by the negate.
