On May 5th, 1818, Karl Marx, hero of the international proletatiat, was born. His revolution of Socialist theory reverberates throughout the world carries on to this day, in increasing magnitude. Every passing day, he is vindicated. His analysis of Capitalism, development of the theory of Scientific Socialism, and advancements on dialectics to become Dialectical Materialism, have all played a key role in the past century, and have remained ever-more relevant throughout.
He didn't always rock his famous beard, when he was younger he was clean shaven!
Some significant works:
Economic & Philosophic Manuscripts of 1844
The Eighteenth Brumaire of Louis Bonaparte
Critique of the Gotha Programme
Manifesto of the Communist Party (along with Engels)
And, of course, Capital Vol I-III

The solution to ignorance is education, not humouring the ignorant. People need to have a basic understanding of the world around them if they are to improve it in any manner. Unfortunately, that involves learning some technical terms. Yes, some people will be confused, but realising that you are confused is the first step in learning something new.
One plus one is two, not three or twenty six. If a bunch of people go around thinking that one plus one is three, that has no effect on reality. Such people must be educated as necessary, yes, but we should not avoid speaking the truth out of fear of confusing them.
Oh no, I understood what you meant. But I feel that OP's approach is correct. They used the words correctly, so that those who already know the meanings can understand what they are saying. Some people did not know what 'capitalism' meant, so they critiqued the meme based on their own understandings. Then OP was able to explain to them the correct meaning.
Returning to my analogy, let us say someone is teaching that 2 + 2 = 4. They can say, 'you already know that 1 + 1 = 2, now multiply both sides by 2'. If a student does not know that 1 + 1 = 2, they can then explain it.
A meme can have only so much text. If they had to derive everything from first principles each time, we would get nowhere.
