Did you actually read the article you linked here? Or just looked at the headline and thought "Oh yeah, this proves my theory, which I pulled out of my ass, based off of nothing - just some opinions of people who have general learning disability"? The only thing author is complainning about is pronunciation, which is far from perfect in English.
Some quotes from the article:
"Some people say that English has complicated grammatical rules, but this really isn’t the case. For example, the verb “to be” has the most forms an English verb can possible have: be, am, are, is, were, was, been, and being (i.e. 8 different forms, while most verbs have just 4).
On the other hand, French être (to be) has 40 different forms! (Just for fun: être, étant, été, suis, es, est, sommes, êtes, sont, étais, était, étions, étiez, étaient, fus, fut, fûmes, fûtes, furent, serai, seras, sera, serons, serez, seront, serait, serions, seriez, seraient, sois, soit, soyons, soyez, soient, fusse, fusses, fût, fussions, fussiez, fussent). Conjugation of verbs is much easier in English than in probably any other Indo-European language."
"Although many people complain about the English system of tenses, it is just necessary to understand what the grammatical constructions are supposed to express (without trying to directly translate everything into one’s mother tongue); for example, the phrase “I have been doing something” conveys the idea of doing something continually for a period of time in the past (and usually also continuing the action in the present). Once you understand the concept, it is much easier to apply it to any verb than in most other languages, simply because verb conjugation is much simpler."
"Similarly, English has no genders and only three different articles (the, a, an); or five, if you count the stressed variants separately. The form of articles doesn’t change according to the function of the noun in a sentence. Compare the two following sentences in English and in German:
The table is big. Der Tisch ist groß.
I like the colour of the table. Ich mag die Farbe des Tisches.
It’s on the table. Es ist auf dem Tisch.
I see the table. Ich sehe den Tisch.
In English, “the table” remains the same, whereas in German “der Tisch” (the table) changes according to the function of the noun, and this was just the pattern for masculine nouns; there’s another one for the feminine, neuter, and plural ones, giving 16 forms altogether to be remembered for what would be just “the” in English. The same applies to adjectives and other parts of speech, so English grammar can actually be considered quite rudimentary in comparison to many other languages."
It's funny how you ignore all the arguments, explaining WHY is english easier to learn than other languages (you find the very same arguments in my posts and the article you looked up - and look, I get that learning a new language whatsoever is hard for the most people, but english IS the easiest one to learn), and come back to "people I talked to said..." when you, yourself have obviously NO experience learning a foreign language. And no, majority of the world doesn't consider English a hard language to learn. A bunch of your friends is NOT a majority of the world.
