While characterizations depicting
Romano as an easily irritated and rude person isn’t in whole inaccurate, it’s
nonetheless one-sided and uncontextualized. By that I mean that this type of
characterization erases the fact that Romano’s incredibly sensitive from a lifetime
full of pestering insecurities and fears. He’s bottled up a lot of these
emotions and lashes out as a result. Likewise, it also erases Romano’s loyalty
in spite of his poor way of expressing it.

Let’s unpack what I mean by this.

For one thing, it’s canon that Romano is an even bigger
crybaby than Veneziano.

A lot of this stems from feelings of resentment and
inadequacy that he developed as a child. Rome spent the majority of his time
rearing and caring for Veneziano.

Consequently, Romano develops an inferiority complex and
feels inadequate compared to Veneziano.

What doesn’t help is that Romano placed second again when
invading countries preferred Veneziano over him.

For example, Spain initially wanted to trade Romano for
Veneziano, as Romano’s manners and housekeeping skills weren’t nearly up to
par.

It sounds horrible, but we do get a touching scene where Spain eventually reconciles
with Romano, learning to accept and love him for who he is.

The two meet each other halfway and develop a strong bond in
which they genuinely enjoy living together.

That bond is abruptly cut during Italian Unification, where Veneziano
and Romano are forced together after centuries of separation in which they
rarely saw each other.

Since Romano still had unresolved feelings towards Veneziano,
the two didn’t exactly get along. As such, Romano opts to move to America
instead to look for work. The immigrant life was a scary and unfamiliar terrain
for Romano to traverse. To cope with this, he calls the first person who’s ever
felt familiar and homely to him: Spain.

Point is, even though Romano doesn’t show it, he’s very
sensitive and shows it in ways that aren’t the most obvious.

While I initially rubbed this off as trivial, there are
scenes during WW2 that are particularly important in showcasing Romano’s
vulnerability.

Ex: He cries during the infamous failed mustache incident with Germany.

Ex: He cries and hides behind Germany from France – note that
this is likely indicative of the fact that Romano is reliving the childhood fear
of being conquered and attacked.

Other examples of vulnerability would include him being
sensitive about his height and crying into tears of joy when Grandpa Rome
visits him from heaven.

Lastly, it’s also important to recognize that while Romano
may be rude, even to people he cares about, he’s loyal.

Ex: During the immigrant period of his life, he cheered on
America when the latter surpassed England in industrial production.

Ex: While too shy to do this upfront, Romano looks out for
Veneziano in WW2 by remaining skeptical towards Germany, questioning him about
his intentions.

Ex: Romano tries to save Spain from illness during an
economic recession, which forces him to come into conflict with the mafia, who he’s
normally terrified of.

All in all, it would be unfair to say that Romano’s a prick
without contextualizing this within a broader understanding of him employing a
tough exterior to hide a more sensitive than normal interior.
