I don’t think anybody’s being attacked. It’s a joke.
That said, I don’t find it funny, but that’s just cause it’s contrived.
I still liked this comic a lot overall though.
Hmm… Fair enough, I can see how that is definitely confusing. The pausing bit… I still feel like you would just write parentheses or sets of commas if you wanted any, but it does lend itself to confusion in this regard, when compared with neat and tidy numbers and symbols.

If they had written it as numbers and operators, then sure, order of operations, because you can see the presence or absence of parentheses and fractions. But when talking/reading the equation out loud, everything changes based on how you stress certain parts or make small pauses.
I’ve been working with lots of fractions lately, so when I first read it, I read it as “c plus three (pause) divided by…”, numerator divided by denominator, my d). Only when reading it again, I read “c (pause) plus three divided by…”, my a). I have no idea what they actually meant.
That’s just a single number and not an equation, there is no ambiguous order here.
Why would standard order of operations suddenly not apply, solely because it’s written out in English? When I go to the bank they have no problem cashing a check made out for “Seventy-five and 00/100 dollars.” While anecdotal and no actual math is involved there, I feel like it’s an applicable example of numbers still generally being understandable by the public when written out.
Furthermore, If the asker wanted parentheses when asking the question, would they have not most likely stated something about their desired order of operations?
Edited because: I forgot to capitalize "English" during my autism.

“absolute value of negative eight divided by the square root of four” could either be
abs((-8) / sqrt(4)) or
abs(-8) / sqrt(4).
In both cases, it ends up as just 8 / 2 = 4.
So: 4 = X, where X is…
X = “c plus three divided by negative five squared” could be:
a) c + (3 / ((-5)2))
b) c + (3 / -(52))
c) c + (3 / -5)2
d) (c + 3) / (-5)2
e) (c + 3) / -(52)
f) (c + (3 / -5))2
g) ((c + 3) / -5)2
a) - e) are linear and contain only c, f) and g) are quadratic and contain c2.
When finally solving for c:
a) c = 97/25
b) c = 103/25
c) c = 91/25
d) c = 97
e) c = -103
and the quadratic equations with two solutions
f) c1 = -7/5 and c2 = 13/5
g) c1 = -13 and c2 = 7
TL;DR Don’t spell out equations as words!

Edited because: markdown superscript fixed
“Negative five squared” = (-5)² = 5² = 25.
8/√4 = 8/2 = 4
4 = c + 3/(-5)² = c +3/25
c = 4 - 3/25 = 3.88
