Why don't we (me included) design some online advertisements to promote Esperanto. Then we can go on Reddit and post them for special interest groups.

For example, Ayatollah Khomeni told his followers to learn Esperanto. Therefore, we can make an ad with his pic and his quote about Esperanto. Then we go to reddit and post it on the Muslim (shia sect) page.

Or, we can take this image and give calvin an Esperanto flag and show him peeing on Hitler with the quote that Hitler made about the language:

Then we can post this on the anti-fascism page.

We can make one for the LGBT+ community.

What do you think?

Your examples seem inappropriate. The Iranian government reversed its position on Esperanto once it discovered Zamenhof was a Jew; and Khomeini, as far as I know, is not an influential religious figure for most Moslems - but rather the head of a theocratic state. And Calvin peeing on Hitler? You really think that's in good taste, and will get people to thinking that Esperanto is a serious language?

Unsolicited advertising is, in Esperanto's case, not likely to result in many new learners. The users of the Reddit subforums would probably just get annoyed with you and ignore you - sort of like how Lernu users would get annoyed if someone came on here and started advetising: "Hey, the Bahai religion supports Esperantists! Come on over and convert!" ...

Sorry to be such a downer.
