In order to protest to wordpress, I opened a topic at its forum : http://en.forums.wordpress.com/topic/against-swastika-of-wordpress, calling the users of wordpress services and my friends to express a protestation demanding the withdrawing of this type of avatars.
A guy (he must be from wordpress) answered immediately, admitting the existence of swastika, refering me to the history of swastika as a non-nazi symbol.
Finally, the topic was closed; so it isn’t possible the expression of protest, showing the guiltiness of wordpress.
I appeal to all antifascist people, especially to the users of wordpress services to protest against attitute of the wordpress using swastikas, opening same topics. The internet address is: http://en.forums.wordpress.com/forum/ideas.
The users of blogspot.com can act at the same way, because the comments of wordpress users let the swastika as sign.
I appeal to all antifascists who write in forums to protest, opening same topics.
Down with Fascism – Nazism. Long live Liberty.
