At the time 'anarchist' and 'nihilist' were still used as pejorative general terms for such activists. Of course the greatest 'terrorism' was performed by the governments of the period. Ideology' that is not lived is nothing but hypocracy and ungrounded, intellectual masterbation. Alternative lifestyles without realistic political commitment are impotent, escapist fantasy. Pseudo-anarchists have sometimes adopted such approaches but they are not part of the serious anarchist movement.
Alternative lifestyles are varied within anarchism, they are a matter of individual taste.
Some choose to drop out completely, others accomodate to the existing society and work from within it. There is a great deal of common ground between anarchism and the radical, libertarian wing of the green movement. I think liberal democracy is finished, it will not last far into the next century. Global Capitalism, its foundation, is heading for an inevitable catastrophic collapse. Some of us are working hard to ensure what replaces it is better.
