Perhaps there are some people against Europanto, as there are always some people against, when something new is invented. But I never experienced something like understanding a text I cannot really be capable of (understanding).
And for sure, you are able to find out what "que" means. I think its better to use a language everyone can understand rather than to let the major part of the folks learn a new language.
You surely see my bad english, which was no problem with Europanto.
