arguments against using a swastika to fight zionism

i was just invited to a secret Facebook group
which argues that socialism and fascism are ideologically similar
and which carries a profile pic of the hammer and sickle together with a swastika

the goal of this group is the destruction of zionism which i applaud
but i have respectfully declined the invitation and i cannot forbear to comment
to those pro-Pal activists who i know have joined this group
about the the major difference between these two social ideologies _
to my (perhaps simplistic?) mind socialism is primarily about universality
which has nothing whatsoever to do with the supremacy of one group or culture over any other _ whereas fascism has everything to do with such beliefs _
and in this respect i believe that fascism is in fact closer to zionism than it is to socialism _

some might argue that the end justifies every means of getting there _
and in the desperate situation that the Palestinians find themselves in
such an argument holds considerable sway _
but i wonder how difficult it would be to convince a more moderate audience of this idea when they are confronted with the infamous symbolism of the swastika

more importantly there is a very real danger
that use of such a symbol will play into the enemy’s hands!!
for far too long zionists have got away with murder and pillage
by screaming “anti-semitic!” at anyone who protests against their evil activities
however since the Gaza massacre last year the ‘anti-semitic’ card has lost a lot of its power and i strongly believe that the struggle to detach anti-zionism from anti-semitism will be dealt a serious body blow by any resurgent use of the swastika _

i am more than happy to engage in serious intellectual discussion
with anyone who believes that socialism and fascism have ideological similarities
but i hereby call upon the secret group
to consider the possible ramifications of using the swastika symbol
and to drop it at their earliest convenience _

thankyou for reading
